I do hate the way CC seem to tar all passengers with the same brush. There are rude and ignorant people in all walks of life in all different jobs and its true you don't remember the nice ones particularly but please remember we aren't all the same. I always board with a cheery hello, ask if its the CC's last flight, if they are off tomorrow etc and thank them and wish them a nice day off when I disembark.
Just remember if it wasnt for passengers good or bad, you guys wouldn't be in the job, if you don't like it, find another job.
