One day when I was at work, our drive thru was really slow...so there was this guy at the window and I took his money and all that. Well i look over and he's writing something in his notebook. He puts it up against his window and it said "YOU ARE NO GOOD!!!" At first I was surprised but then I gave him a thumbs up sign, nodded yes and turned away. He got pissed off and left without his food. There are other stories like that but that one was most memorable.
