These kind of cunts have nothing, they are just cunts. The problem is, you could be seriously unlucky and find someone with actual allergies. And that's the real issue, cunts like these ruin how serious matters are perceived for those who are in actual need.

To me this reminds me of a funny situation myself. I went with my wife to a teppanyaki, and as it had to be on the hot plate a girl started to throw a fit. The problem is, staff there doesn't anything except Japanese. So you either manage by language, or by pointing what you want. Eventually it became clear, the girl was a vegan and bitching that her courses all had meat & fish .. The teppanyaki guy flipped off the fish from a sushi in response which caused her to go mental. Fun times.
