According to a recent study, vegetarians have confessed to eating meat after a night of drinking. VoucherCodesPro, a UK-based discount code provider, conducted a survey of more than 1,700 British vegetarians who revealed they chow down on meat when they drink too much alcohol. Don’t tell Morrissey about this!
It depends on how strict a vegetarian you are. Some stuff like soup might’ve been made with chicken stock, etc. I know some who ask the server, and make choices accordingly. Personally, aside from morals – the world is not going to end. I respect it, but have a hard time putting vegetarianism on the same level as those who have serious allergies/risk of anaphylactic shock. Or in my case – thrombosis (clots are only on the outside of the body) to drastically increase risk of heart attack, stroke, aneurysm.
