Went to Whataburger last night. Ordered a Whataburger combo. Went to go for my wallet and found it wasn't there. Went out to the car and it wasn't there. D'oh! Back inside to tell them to forget it. Fellow customer whips out the cash to pay for it. Said, no thanks. He insisted. Incredibly nice. Not sure that I would do that, but it made me feel good.
