when I read the title of this thread, all I could think of was
female flight attendantswearing boots....

as for passengers who don't belong in emergency exit row
seats.... whenever I'm in one of those seats, I always see
flight attendants asking if everyone in that row is willing
to help and can understand English. there was this one
time when someone next to me in the emergency row nearly
got relocated because she refused to put down her smartphone.
the flight attendant became more angry than the Angry Birds
on the young woman's smartphone!
