have you guys ever had people mooch off you for your hookah? I live in a college dorm and smoke with about 10 different guys on my floor. Im friends with all of them, but, as you can imagine my tobacco and coals run out fast. only about 3 of the 10 guys contribute to replenishing my supplies. I proposed the idea of asking for money to one of the guys that never contributes and he got very defensive and said "you better not start charging us" I didnt have "charging" in mind but I would appreciate it if they voluntarily offered cash or supplies. Its a touchy issue b/c they dont expect to have to pay...Anyone have a problem like this before? if so, howd you fix it?
