Dudes who’s entire sense of self is invested in eating meat
This might sound silly. But maybe they enjoy the taste of rare roast beef? Before this “make meat seem like it’s not dead animal” trend, the rule used to be anything over medium was overcooked for most meats. For some odd reason (actually, not odd. freaking additives) a lot of roast beef is sold medium-well. Which is tasteless enough to make someone go vegan!
I don’t understand “yell at the clerks”. I’ve never seen that. But I agree it’s rude. Just **not **because they are buying meat.
