What a....that guy.... If that was MY fiancee....at a freakin' best buy because he has to wait in line?!? That is sooo screwed up. I don't even know where to start.
She definately did the right thing by letting it go at the moment, so good for her. I would have had to fight a strong urge to knock him out and take his gun. Some people. Man that irks me.
I think a report to the police was/is in order....
