Shrug. People who are sick sneeze into their hands. They think they are being polite, but they are coating their hands with germy, infectious snot. They then handle the IFE screen, overhead bin latch and cover, seat belts, air nozzles, light switches, window shades, etc. People poop, wipe their butt, skip washing their hands (or just do a quick rinse) and then touch everything. Yet it's some guy's feet that freak you out? Why?
