Over the last month, I've eaten at the local Back Yard Burger 3-4 times. I've been waited on by the same, polite young man, and each time I've notice that he ended my transaction by swiping a card through the reader. He would then hit a few keys and a 10% discount would be applied. I kept thinking he had made a mistake or they were running some kind of special - then last night it hit me.
He's giving me a senior citizen's discount.
Maybe I'll shave the beard...or just claim proudly Old Guys Rule!
