What happened at the end?
In the last scene at the diner when one of the guys pays with a $1,000 bill, we hear the girls fall off the bar stools. Two possible ideas come to mind. Was it that they fainted on the sight of seeing such a large amount of money? Or were their drinks poisoned? I'm not sure if the latter happened or not, but it would work in the storyline as a way of the guys killing their wives to get their money back.
Or was it just fainting from the sight of a $1,000 bill.
"What happened to my sweet girl?"
