Yeah I've started doing no tip on the iPad, but I feel guilty every time, which is ridiculous really even though I wouldn't have thought twice about it 3 years ago when I wasn't prompted to leave a tip. Also tipping a bartender for popping a cap off my beer or pulling a lever on a tap... Also tipping in a full service restaurant is equally fucking weird. Like why am I paying you a percentage of the food I order, why don't I just pay you (how good a job you did) * (how long I sat at your table).
