It's not a self-contained TPN compounder in a hospital cleanroom. It's a machine that has many parts that get wet with sugary water. It has parts that need to be cleaned that seldom are, and judging by the average fast food employee, would probably be better off left alone than further contaminated by them attempting to clean it. Google "soda fountain mold" and you will be stunned to see how nasty these can get. I don't eat fast food often, but I skip the drink unless it's from a meticulously clean place.
