People with over-the-top food aversions.
I mean, I can understand not liking things, some foods just taste like shit.
However, there is not much worse than trying to take a girl out for a nice dinner, only to be shot down with every food option you bring up. Sushi, no. Thai, no. Indian, no. Holy fuck, have a sense of adventure, there are so many wonderful tastes from different cultures.
Or, finally picking somewhere, and having them completely butcher what was listed on the menu to satisfy their retarded eating habits. What an insult to the chef, so embarrassing.
