I've found a lot of places show 18/20/25% now. I went out on Saturday and 18% was included, which is fine because we had a large party, but then the tip screen was for an additional tip on top of that and it still suggested 18/20/25%.
I draw the line at anyplace where I go to a counter, order, wait at the counter, and then pick it up. No tips. Especially here where we don't have "tipping" wages.
