What gets my goat is passengers who sneeze w/o covering their noses and then you feel the tiny droplets hit your skin. Also those who have just ingested a heavy, garlic-laden meal and their breath reeks of it. I hate flying/airports and not because of fear!
My biggest pet peeve is the smelly food people. You know you’re coming into a confined space, so how about a little forethought when choosing that Caesar with anchovies? Also irritating...the people who sit holding their food in the boarding area for half an hour and then have to bust open their stinkbombs the minute they board. Why couldn’t you eat that in the boarding area?
