Most small businesses like that have maximums they want in the ‘till. If she allowed that maximum to be exceeded, then she did not comply with her guidelines.
If it was after hours and the guy demanded she fork over all the case, then your thoughts could be more reasoned. You obviously follow orders.
If it was during the hours the business was open and he just demanded all the cash in the drawer, then she’s not quite so innocent.
It doesn't matter. Their young female employee/mother got a gun shoved into her face by who knows what type of violent savage. And the young employee then gets fired because the biz possibly lost too many dollars?
Sue these greedy biz owners until their out of business.
You're in a some weird world there. Trust me.
If it were my daughter who had to go through this violent life threatening event, and then hear these SOB's fired her, I would personally find her the best attorney possible and go after them with a burning vengeance.
