Like WTF!? "Starving? You can't afford 'good' food working here, but you can afford the food you're already making!"
Also, I worked in a lot of kitchens before and never once paid for a meal. "Damn son, didn't mean to put cheese on that! Guess I'll have to make another one."
Never pay a company for your food if you're the one making it.
I have worked at two fast food restaurants in my life.
At Subway, we got a six-inch sandwich and unlimited drinks free. At Dairy Queen, we got all purchases half-off, any food that sat sat around the kitchen for "too long" and unlimited free drinks.
I have never seen someplace outright offer free food.
