Ask if it weighs out? If you know it don't say it don't look right and if he won't correct it you don't want it. Sent from the Green Green Garden of Eden
Dress up as a boxer, get your hands taped up, gloves, everything. Then if its a short sack tell him to square up!
When I first read the title, my immediate thought was, "don't be a bitch." I'd just be like, "Really? Feels a little light, man. Can you weigh it out?"
Literally go hey man I think te bag is a little short, if ur dealer beats u up after u ask, well he's a really shitty dealer then. Also u should ask to watch him weight it next time if u think its light
personally i'm not scared of getting beaten up by my dealer, but it is awkward to bring up, so just be polite and say, o think you made a mistake, i payed for X amount, could you weight this out to make sure its right. if he does refuse ditch that dealer.
