In the food-service industry, when a steak is cooked incorrectly (more often than not, overcooked), a new steak is cooked for the guest. The original over-cooked steak, often un-touched, or merely sliced into to determine wellness, is perfectly good for eating. As a server, mistake steak is an annoying (because of the lowered tip received from the guest) mistake, but also a delicious one.
The kitchen fucked up my steak order for my table again, god damnit. They ordered medium-rare and this is medium-well. Oh-well. While they're cooking a new stake, I'll eat this mistake steak. OM NOM NOM.
