The taco bell near us is pretty bad, a good third of the time they don't give us an item. My father told me years ago that what they do is not ring up an item in the order, charge you the full price of everything, and then pocket the change. Last time I was there, I heard the total, my boyfriend gave the bills and I counted out the change (which I'm really good at because I work retail). He tells me that I counted it out wrong, so I grab a few more coins, and he hands them to the employee. I go over it all in my head, realize that whatever I had at the time had been correct and that the employee had stiffed us our change. It's a few cents mister, do you really need it that badly that you have to steal from customers?
