A TSA checkpoint is a bigger germ farm than the monkey in Outbreak. If you don’t have PreCheck you have to take off your shoes, and the checkpoint floors can be as bad as a domestic airline lavatory at the end of a Hong Kong flight.
Your fellow sick passengers touch the bins, they even put their dirty tissue sand handkerchiefs in them before going through the nude-o-scope pockets empty. TSA provides their employees with blue gloves, not you.
