Digital tip prompts have spread across payment screens, including some self-checkout systems where the customer scans, bags and pays without a traditional cashier. That makes the familiar request to tip the person providing service feel unusually complicated.

A September 2025 Adyen survey of 1,001 U.S. adults found that 64% would refuse to tip at self-checkout. The same survey found that 13% tipped more when they felt watched by a cashier, friends or a date, illustrating how the payment screen can turn a voluntary choice into a social-pressure moment.

Why the screen matters

Research published by Ireland’s Competition and Consumer Protection Commission on January 28, 2026, reached a related conclusion about digital tipping design. Two-thirds of respondents said tipping was becoming less voluntary, while 75% wanted businesses to make opting out easier. The regulator recommended that any “No Tip” or “Skip” option be at least as obvious as the suggested amounts.

The cartoon pushes the self-checkout contradiction into workplace territory: if the customer is doing the cashier’s scanning and bagging, perhaps the machine should stop treating the customer like a guest. The kiosk, shopper and dialogue are fictional satire. The joke does not claim that shoppers are legally employees or that any particular retailer handles tips in a specific way.
