My chiropractor stopped eating out years ago, the commerical prepared food is all crap. Basically you have poor people who could care less and they mostly sick and use chemical sprays on everything to stop you from getting food poisoning and passing on the flue to others.
For some reason the cheap joints seem to have a hard time keeping a cook and it seems many of the younger drug addicts that never get a real job because they can't pass the pee test, can get jobs in the low paying restaurants and hotels as cooks. You do not want to know what these folks do to the food for laughs!!!
