Hmm, well, yes, I suppose for a nice lunch I'll leave a couple of dollars, and usually it is under $10 - $20. Like at JapaDog lol.
But for nicer dinners, when the bill is nearing $100... I usually don't give $20! I don't order alcohol and I don't tip 20%... I wonder if they hate me
Must be nice for everyone else (well most Countries) in the World outside North America to not have to worry about tipping.
