I work at a Thai restaurant and we prepare our entrees with a spice scale, 1-10. One day I had a middle aged Caucasian man order a meal where he asked for a 15. Naturally, I reported to the chefs and they made the spiciest dish I have ever encountered. While talking about his experiences in Thailand, he started to criticize the food served around him and mentioned that there is no dish that will be too spicy for him. Well, the dish we served was his limit. He took three bites and began to throw a tantrum. The guy then took his plate and threw it on the ground then stormed out of the restaurant.
