A Wendy's restuarant in NEPA. I ate there and about five minutes later had a severe allergic reaction to something in their food -- a reaction I'd never had before. So, I figure it was just unsanitary cooking conditions that caused the reaction. Needless to say I'll never be eating there again!!!
Also when I was a teenager I worked at a high-class restuarant, formal dining, which will have to remain un-named, and they reused partially eaten bread, butter and salad dressing left over by the customers. It was quite disgusting!
