I find it annoying that more and more takeout places have a tip jar. How much are you supposed to tip on a sub?

Under $8, whatever small change I have... $0.50 or so usually. Often enough, nothing. After that, approx. 10%.

I think the most common answer is "whatever coins you happen to receive as change"
