How much does FC tip when eating out?

I am a measly tipper unless there is a reason to - like over and beyond service. 

My wife isn’t necessarily a fan of me doing that. Can someone convince me otherwise?

Unlearning. Full time product manager. Part time builder/tinkerer on farcaster. Bots: @nftsoffc.

I tip only when I like the service. Which is often. Rarely more than 15%. Often 10%. 

Waiters in Europe earn proper salaries. Service fee is often included in the bill. 

I do not appreciate the way it is handled in US.
