Oh yeah... I was once at an Econ Minimart. The cashier had
accidentally given a woman less change than what was expected. The
woman immediately scolded the cashier with all sorts of vulgarities
at the top of her voice even though the cashier had apologised
profusely and was doling out the correct change.
The idiot-of-a-woman kept screaming about how she had been cheated
and about how she should call the police to arrest the cashier.

The other customers in line tried to calm the woman down and
explain to her that it was just a misunderstanding, but she was
still screaming after ten minutes. In the end I grew sick of
waiting and left without buying anything.
Sheesh... some people... they think that the universe revolves
around them...
