There was a report on Inside Edition about street food vendors in NYC. They showed them: picking their noses scratching their ass touching raw meat with gloves and then serving food with the same gloves. one guy went inside to use a bathroom at a museum and did not wash his hands. one guy was sitting on a bench resting and running his fingers through his bare toes. one guy licked his glove to count money and did not change it. There was more but it was so gross that I am not eating street vendor food ever again.
