That's still kind of a dick move, man...
That's the social contract -- you go to a full service restaurant, you tip 20% of the bill.
I can understand for things like even retail and other non-traditional PoS stuff but for full service dining, this isn't new.
If you want to opt out of participating in the whole tip structure there, then you probably should opt out of participating in full service dining as well.
I've actually decided the real problem is clueless people like you trying to tip police others over immaterial minutia like exact tip percentage. Do my napkin FFS and see for yourself what my percentage averages out to. You're the ones manufacturing frantic guilt. It's like atheists and unknowns. Christ.
When did it go from 15% to 20%? Is it because people don't tip in cash anymore, making it more difficult for service staff to evade taxes?
Isn’t the idea that servers knowingly make a gamble that they can generate more from tips (performance) than less than minimum wage?
So if you order a drink that costs $1000, the server should get $200 for that?
