I feel your pain, and I'm concerned about someone who works at a bakery not knowing where ingredients came from.

I'm not even vegetarian but I worked at a vegan/vegetarian restaurant where random people would come in to complain we didn't have any meat on the menu. Like legit walk up to the host stand, pick up a menu, shout "Is there any meat?" and leave in a huff when we tell them no.

Their loss. I made a kick ass curry and put black bean burgers on the menu.
