I agree.  If I was sitting next to him and the plane was leaving late, he would get an earful.  Men acting like jerks to FAs are just plain unmanly.  I like to think of myself as a gentleman (sometime I pull this off); I wear clean clothes, save my excess drinking for home life, and say "yes, mam" and "thank you."  Funny thing, after flying about a bazzilion miles no one has threaten to kick me off an airplane.  Men, act like your mother is the flight attendant!
