I think they're everywhere...and every walk of life has it's fair share of miserable gits to be honest.
You have only to browse thru some of the posting especially those around the various airlines out there and in particular Britain's favourite airline and you'll see loads of them ranting on ..
Infact my BF whos along haul pilot for the very same airline is a prime candidate today..better be careful what I say as he posts here! You know I love you really hunni!!
