I have a friend who drove a milk truck delivering to stores and restaurants.
One day I mentioned that I was taking the wife out to dinner and named the restaurant I was taking her to.
He looked at me and shook his head.
I named another and again he shook his head.
Another restaurant, another head shake.
On the fifth restaurant he finally nodded.
He ended up giving me the name of one other restaurant he would eat at.
His last words were “eat anywhere you want but DON’T think about what goes on in the kitchen”.
What was surprising was that all the restaurants he shook off were pretty upscale places that were frequented by the local royalty.
I used to work for register company, i rarely ate at any of restaurants where I serviced equipment. I saw what went on in kitchens
My brother repairs industrial food equipment, he is the same way. Will not eat out at most restaurants he has worked in, says he has seen too much.
