I agree completely, all money has to go in the register....
I would think she put the entire $20 in, and had no way of knowing if the purchase was only $15 but, you don't get to take the $5.00 out and put in your pocket.
It still belongs to the store.
Besides, he wasn't there anyway !!![]()
So then wouldn't that make it less likely for her to make up the story about seeing JLY that morning then? If she pocketed the 5 (not 15), then she would not have told such a story about him paying for 20 and only pumping 15.
