My brother works as a plumber and he’s seen grease traps and “back of house” at a lot of restaurants. On the rare times he eats out, he prefers to eat at big chain fast food stores.

My brother worked at Hardee’s in the early 90’s, and they had awards for cleanest location and some punishment for those that didn’t meet their guidelines. His location won a lot because they all ate there (big discounts).

Food safety is limited to hygiene, and ignores factors such as calories, nutrients, vitamins, etc.

Eating only store-bought, hermetically sealed chocolate would rank excellently in terms of food safety.
