Speaking of obtuse PA comments:
I cringe every time the F/As Pa; " you should now be comfortably seated..." What if I'm stuck in the middle seat between two large , smelly people? Should I ding the F/As and tell them I'm not comfortably seated?
or
"please ensure your seatbelt is safely fastened..." What, is there another way of fastening the seat belt?
or
"I'd like to welcome you aboard.." OK then, welcome me aboard, don't tell me you want to welcome me aboard. Is it you can't welcome me aboard but someone wont let you?
