That's really funny! I know of a recent story just like that! A friend of mine went to the Czech and gave a waiter at a restaurant an usual amount of tip, nothing special, and at the end, the waiter guy called him outside the place and gave him what looked like 30 grams of weed (more than an ounce)..All I can say is that four people ended up giving me free weed in the czech....when i only asked for it one of the four times. Apparently it is a custom there to offer weed to others if you have it????
Man I wish it was like that in cali!..
