Enough of the English lessons already!
Back to the topic..........................
Now, while the woman who ordered the pizza was wrong to shove it across the counter at the pizza person, hey..........it was just a pizza, and won't take more than 2 min to clean up. Yeah, it's a pain she was such an ass, but if you work in a customer type business, you gotta accept the fact that some idiot will come into your establishment and be an ass. It happens.
The pizza employee going out to the parking lot and shoving her? That was wrong, and the employee should be fired at a minimum, brought up on charges if there is justice. She's lucky the customer who was shoved didn't want to call the police and wait for them, because I'm pretty sure that place has cameras to record incidents, and if the police had seen tapes of what happened (even if just the video the other person was taking), the employee would have been arrested for assault, and if the customer had decided to sue, they would have been able to get some fat bank from the franchise owner.
Believe it or not, in this case, I'm on the Karen's side.
