Thank you for the info, Housetek.
Some of it is common sense, and some were really useful tips as well (I didn't know about #3, #4 and #13). I got to experience #18 first-hand the other week when I went to our local Sushi-bar. I left with the food without waiting for my change, and the owner's daughter ended up running after me out in the street. I'm not sure who was more embarrassed, her or me...
