Think about the guy who didn't wash his hands before getting his burger and used the spoon on the condiment bar minutes before you.
Think of the hundreds who had a nice sitdown in the bathroom who didn't wash and opened the same door you just opened.
Think about the sneezing coughing runny nosed 9yo who grabbed the same restraint bars on the rides you have.
Think about that dollar bill and quarter in your pocket.
No. That kind of thinking would keep many people from engaging in life ... I still will visibly cringe and move away when a person is obviously ill.
