If you make a deal to sell something to someone, you set up a time/day to sell them to that person. You've given that person your word that you'll sell it to them and you're shitty if you sell it to someone else after you promised it to them. if they dont show up when you decided to sell the shit then that makes them shitty. either way if you're gonna do that to somebody at least call and let them know.

i agree with vader... that dudes a chump
