If you have never bought anything at a airport--kudos. If you don't find airports or planes or cruise ships or trains a giant cesspool of germs--we just disagree. Maybe Todos is right or wrong on airport sale or airport vending?? But for some reason airports seem to have shops that sell things. Vending machines that sell things. There is/was?? a PGA store in DFW. Some airports have theatres. Others have medical clinics. Any convenience store at airport sell aspirin/ibuprof?? For some reasons these stores carry these products
