My statement is that everyone here was an adult and they all made poor choices.
Granted that the dudes action was small, but now that I think about it that was actually what started it.
It should have stopped with just asking the cashier how many bananas he paid for.
They did not even need to bother asking him and risking someone just thinking they were being called a thief.
I know that is how I feel every time I get asked for a receipt, and I am a middle aged white guy in redneck country, god only knows how often he probably has to deal with it.
