Vegetarians and vegans are well aware how few options there can be when they go out to eat. Especially if you're outside of cities and neighborhoods accustomed to catering to special dietary needs and requests. It's easily one of the worst things about being a vegetarian. (It's also a not uncommon complaint non-vegetarians have about going out to eat with vegetarians.)

A lack of options is not something most meat-eaters have to deal with. For the majority, any restaurant menu is an endless cornucopia of options, even if you're eating at a vegan restaurant. Yet, one diner decided it was ridiculous that a vegan restaurant didn't carry meat for the non-vegans that might stop by.

"No option for non-vegan," they wrote in a TripAdvisor review of Manchester's V Rev Diner. "I find out once I had been there."
