30 years ago while I was waitressing to pay for college, I worked in a very upscale restaurant. The fact that it was so refined only makes this worse as the folks around the customer fled the restaurant.
An ederly gentlemen wanted to send back his food. I asked him why. He screamed that it tasted like crap loud enough to be heard in 3 states. He then vomitted on the floor. When he finished wretching, he took a sip of water and proceeded to keep eating.
I was only 19 at the time. The manager/owner had all ready been standing by myside when the guy started screaming. It was too much for me so I went into the kitchen. The manager/owner started to clean up the mess, then handed the elderly gent a knapkin and suggested that he get to work. He, and a few dozen other folks, simply left without paying. It was a complete fiasco.
