I'm going to call out a customer when she dumped her basket of groceries in a freezer bin
Why do you want to call out the customer?
It is such bad manners to waste all the groceries.
She had no right to waste all of the groceries in the freezer bin. It is typical to put items back if you no longer want them.
I know, I can't believe she would do that. I just want to call her bad name.
I can understand why you would be upset about her not putting things back. Maybe she doesn't know that she had and it would be good to explain that to her.
