I remember the slogan for Steak N' Shake, where they had huge plate glass windows right in front of the grille where anybody could walk right up and watch the food being prepared, the resulting slogan?
"In sight, it must be right"
Now these goons at Dunkin Donuts?
Unspeakable.
"If you don't see it, we will pee in it."
I used to hang out at this diner in Chicago where you could see the cooks working in the kitchen. Caught one of them picking his nose while cooking.
