One day, chilling behind the counter at my liquor store job, two middle aged guys walked in all wobbly and flushed. Placed two 'light' tall cans by the till and had a short but cute fight over who was paying. Umprompted, told me all about how they started going to crossfit together and how great crossfit is and on Sundays they treat themselves to a couple beers to go with the high protein lunch they make together.
I saw them often after that, they were straight as hell, and the loveliest damn boys I'd ever seen. I loved hearing about how much fun they had at crossfit.
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.
