Those are violations of the core Pot Head rules
1)Your Weed your responsibility. (if you are holding for a friend and you see a cop, and he says move you say how far...)
2)Never steal or smoke with someone unless you throw down or are in agreement to get smoked out (the other person says that they are going to smoke you out).
...shit i can only remember 2 right know.

But yeah, ditch the stingy chick and the retarded guy. Bad things can happen if you keep smoking with them.
