A real life example of what can go wrong, recounted on a Sacred Forum by a rueful Player1:
(after a run)
Player1: You're pretty handy in a fight.
Player2: Thanks! I've managed to get some decent items. That helps.
Player1: like what? (Tosses moderate item on the ground) This is quite handy.
Player2:(Grabs item. Drops it again) Yeah that is quite good. (Drops very impressive item) I have this!
Player1: (Inspects item, then drops it) That's almost as good as I've seen anywhere. Look at this though! (drops item)
Player1: (Grabs Item) SUCKER!!!!!! (Drops network connection).
