I do eat out now and then. Just a couple of places where I am comfortable. And, I never, ever, denigrate the help and tip appropriately. I will neither pay for, nor send back to the kitchen, a badly prepared dish. I will voice my complaint to the manager, leave and enjoy a bologna sandwich at home.
As a rule I do not frequent those understaffed, overcrowded fast food steak houses and the like. Seat turnover is the driving the force I find, not food prep and service. I cannot, however, bring myself to pass a sidewalk sate vendor in Asia. I just try not to guess at the meat and its origins. Same with "Shashlik" vendors in former SSR countries. Too tasty to be picky about. The aromas overrule my usual reticence and health concerns. Stupid for sure but, sooooo tasty.
If I can see the food prep as I wait for an order, there is not a Carolina pulled pork joint, no matter how unkempt that I can pass by. Sometimes you just have to suck it up and take a chance. My nose and stomach will frequently overrule my good sense. It's a weakness I accept. I'm trusting to an iron stomach which was toughened up during years of good food, probably ill-handled, in a host of greasy spoons while walking foot patrol in a seedy part of town.
An aside: Captain, I am trying to lose weight. Not too arcane I hope.
