We went out for dinner at a restaurant and those buggers tried to slip an automatice 15% tip onto our bill!! This really upsets me because we always leave our tips on the table in cash....if I hadn't looked close at the bill I would have ended up tipping 30%..... >:(

When we get good service and good food we always tip, but I think this is a deceptive practice.....the same thing happened on a chinese delivery one time and the bugger got double tipped!!

Any thoughts on this and what an appropriate tip is?? Sometimes when the bills are a little on the high side giving a 15% tips really stings.
