Creature of Habit

One of the advantages of being a creature of habit is that you know exactly how much things should cost. I typically grab lunch at Jimmy John's at least once a week. I pretty much order the same thing (No. 5, no onions, no cheese). And one of the cashiers knows my order by heart. But today, when I walked into the restaurant, I was greeted by a cashier I didn't recognize. And sure enough, when she rang up my order, she tried to charge me an extra dollar over the usual cost. So, I looked at her and calmly asked 'Are you sure that's right?' She says, 'Yeah.' But then her co-worker leaned over and pointed out her error. So then she had to void the transaction and start all over. And while she was doing it, she mumbled something about how the keys on the register tend to get stuck, and that's why she over charged me. Umm, yeah...right. It would've been nice if she would've just apologized for her mistake, instead of blaming it on the machine.
