IT is dash 8 humour not understood by all. Immediatly after my "please continue to remain seated and observed the fastened seatbelt sign" pa there are often those folks to whom rules don't apply immediately jumping up and wandering around the cabin, with various excuses. I had to smile on a 30min SYD-CBR at a recent one that excused himself with " I just wanted to go to the toilet quickly so that I didn't get stuck behind your trolley while you were doing beverage service" Frequent flyer???
