when going out for a meze with your friends or relatives, keep an empty crisp packet in your pocket. when the waiters start bringing the food out, place one of each item in the crisp packet that you now have placed between your legs.
then when you leave the restaurant you just look like you are carrying a bag of crisps, rather than making you look like a scrounging, fat, greedy git who has helped himself to the left overs
ps
i have never done this before honest !!!!
