i think the commentor is referring to how you shouldn't piss off ppl that are cooking and serving your food because they might mess with your food or something. i don't believe they are sticking up for the abusers, just that you shouldn't piss them off while they have a chance to mess with your food.
like how you should be polite to your waiter at a restaurant and don't be rude to cooks and servers of your food. there were some incidents at a KFC somewhere that was caught on camera where the ppl in the kitchen were scraping ppl's food on the floor and then serving it to ppl, also a lady who adjusted her pad and then prepared food without washing her hands... also they could spit in your food or something...
I know what Blondina did was courageous but never, like ever, piss off the people who makes your food.
Especially in this case, Blondina pissing off the inn's owner and cook. Like seriously. ( ̄∇ ̄")
