The Hidden Fee at the End of Your Restaurant Bill
Sunday App charges diners a mandatory “Platform Fee” they never agreed to, revealed only after customers have already committed to paying.
Sunday App, Inc. built a restaurant payment platform that deliberately hides a mandatory “Platform Fee” until the final moment of checkout, after diners have already scanned a QR code, navigated multiple screens, and entered their payment information. This is not a minor oversight; it is a calculated scheme to extract revenue from restaurant customers who have no real choice but to pay. Thousands of diners across California, Illinois, and nationwide have been overcharged, and the total harm runs into millions of dollars.
Diners deserve to know the true price of their meal before they commit. Demand transparency. Share this story.
| 01 | Sunday App adds a mandatory “Platform Fee” to every restaurant transaction processed through its QR-code platform, without disclosing this fee before consumers begin the checkout process. | high |
| 02 | The fee is revealed only at the final step of a multi-step payment flow, after consumers have scanned a QR code, navigated multiple screens, and entered their payment and personal information. | high |
| 03 | Sunday’s payment interface displays a running total that implies the consumer will pay only for their food items plus government taxes, never alerting them to an additional mandatory charge. | high |
| 04 | The fee varies in amount based on the consumer’s subtotal rather than any fixed operating cost, demonstrating that it is an arbitrary profit-extraction charge rather than a legitimate platform expense. | high |
| 05 | Sunday does not explain what the Platform Fee funds, how it is calculated, or why it is mandatory, either during checkout or on post-purchase receipts sent to consumers. | med |
| 06 | The platform is endorsed or required by many restaurants, meaning consumers often have no practical alternative payment method available at the table, leaving them trapped by the fee once they have committed to the checkout flow. | high |
| 01 | Sunday exploits “consumer inertia,” the documented psychological tendency for people to complete transactions they have already invested time in, even when they discover an unexpected charge at the last moment. | high |
| 02 | On post-purchase receipts, Sunday buries the Platform Fee as a line item positioned after food items, taxes, and all other charges, minimizing the chance a consumer will notice it and question it. | med |
| 03 | The variable, percentage-linked nature of the fee means Sunday collects more money from larger bills, generating significantly more revenue from consumers with no corresponding increase in service or cost to Sunday. | high |
| 04 | Sunday advertises its platform to consumers as a faster, more convenient checkout experience, but this “convenience” conceals a mandatory cost that consumers would not knowingly accept. | med |
| 05 | The complaint estimates that across thousands of transactions nationwide, the undisclosed fees total in the hundreds of thousands or millions of dollars, representing direct wealth extraction from restaurant diners. | high |
| 01 | Plaintiff Hoke paid $4.99 in undisclosed fees on a $184 restaurant order in Los Angeles in December 2025. He states he would not have used Sunday’s platform had he known about the charge. | med |
| 02 | Plaintiff Shafer paid $0.69 in undisclosed fees on a $39.95 order in Chicago in December 2025. Like Hoke, she states she would have chosen a different payment method had the fee been disclosed upfront. | med |
| 03 | Because many consumers only discover the fee after completing their transaction, they have no practical recourse, no ability to cancel the payment or choose an alternative, compounding the financial harm. | high |
| 04 | Sunday’s undisclosed fee also distorts price competition: consumers cannot accurately compare Sunday’s true cost against other payment options because the real price is hidden until it is too late to act on that information. | med |
| 01 | Despite clear FTC guidance from 2013 requiring that all material fee disclosures be made before consumers commit to a transaction, Sunday designed its checkout to withhold the Platform Fee until the final payment step. | high |
| 02 | Sunday has not amended its platform to clearly and prominently disclose the fee before checkout begins, despite regulatory focus on junk fees from both the FTC and the White House from 2023 onward. | high |
| 03 | The company provides no explanation of what the Platform Fee funds, either on its website or in post-purchase communications to consumers, a basic transparency step it has chosen not to take. | med |
| 04 | Sunday did not respond to the CLRA pre-suit notice sent by plaintiff Hoke’s counsel demanding that it rectify its pricing practices, forcing the filing of formal litigation. | high |
| 05 | Many class members do not know their legal rights have been violated, meaning Sunday continues to benefit from consumer ignorance and the practical difficulty of pursuing individual claims for small-dollar harm. | med |
| 01 | Sunday’s scheme is a textbook example of “digital drip pricing,” a deliberate strategy of advertising a low price and adding mandatory charges only as the consumer reaches the point of no return. | high |
| 02 | The practice undermines the free market’s price-comparison mechanism: consumers who cannot see the true cost of a service before committing cannot make rational economic choices between competing options. | high |
| 03 | The White House and the FTC both identified junk fees as a systemic threat to consumer welfare and market competition in 2023 and 2024, yet companies like Sunday continued the practice, betting that enforcement would not reach them. | med |
| 04 | The class action mechanism exists precisely because individual harm of $0.69 or $4.99 is too small to litigate alone, but when multiplied across thousands of transactions, the total represents a significant and unjust transfer of wealth from ordinary restaurant-goers to a venture-backed tech company. | med |
“Sunday has engineered a ‘pay junk fees to play’ scheme. Consumers cannot use the Sunday app/payment platforms to pay for their orders unless they pay the junk fee unilaterally set by Defendant.”
💡 This framing from the complaint strips away any technical ambiguity: Sunday built a system where the only way out is to pay a fee the diner never agreed to.
“Sunday prioritizes hidden revenue over transparency, exploiting consumer trust at each transaction.”
💡 Every single use of the Sunday platform is, according to the complaint, an act of exploitation, not convenience.
“This is a classic form of digital ‘drip pricing’ that exploits consumer inertia and effectively deprives consumers of meaningful choice.”
💡 The complaint identifies the precise psychological mechanism Sunday relies on: people who have already committed time and effort are unlikely to abandon a checkout at the last step.
“The variability of this fee underscores its arbitrariness and confirms that the Fee is not a fixed charge tethered to any legitimate, unavoidable cost of processing a transaction.”
💡 A fee that scales with your bill total, rather than with actual processing costs, is not a service charge. It is a profit mechanism.
“The full amount of losses has not yet been ascertained, but which are believed to exceed the hundreds of thousands, or possibly millions, of dollars in the aggregate.”
💡 What looks like small change per transaction adds up to a massive wealth transfer from restaurant-goers to a tech company.
“The economic harm is compounded because many consumers only discover the fee after completing their transaction, leaving them with no practical recourse.”
💡 The harm is designed to be irreversible. By the time you see the charge, your money is already gone.
“This coercive setup turns convenience into a trap, forcing consumers to pay more for no added value.”
💡 Sunday markets itself as a tool that benefits diners. The complaint argues the opposite: the fee is a pure cost with no consumer benefit.
“This deceptive practice is intentionally designed to catch consumers off guard and extract additional revenue without their informed consent.”
💡 The complaint does not characterize this as an oversight or a poor UX decision. It calls it intentional deception.
