> Try giving a tip

No. Tipping is bullshit and you won't convince me otherwise. When I go a restaurant I want to have a nice experience, not deal with a pushy waiter begging me for a tip like a Syrian refugee begging for a coin because he hasn't eaten in days. "But if I tip I get a bigger kebab" yes, and you ruin the experience for everyone else because you teach service providers that displaying one price but actually charging another is a good business practice. If you want a bigger kebab, why don't you just pick it from the menu?
