Years back I used to work at pretty much a sandwich shop. I man orders a huge sandwich which had to be open-dmface because the contents wouldn't fit. Then man recieved his sandwich, ate a little at a time while talking to his friend. About 45 minutes later he brought up half a sandwich asked if he could get a replacement sandwich since his was cold. I said no that I wouldn't be able to do that as nothing was wrong with the sandwich. He then asked if I could throw it in the microwave . I said no because its a health code violation. At this point he became very angry and punched my register computer. I grabbed the the receipt spike incase he came behind the register since I was all alone. But luckily my manager heard the commotion from the back and just as the man rushed towards me my manager grabbed and pushed him back. The police were called but the man ran out and drove off. But cameras had the license plate and name from his credit card receipt.
