I used to know an ex-hostie. She had a slight lisp, had been told to avoid doing the cabin announcements, and succeeded for many months. Eventualy came the time when she could avoid it no longer. So she wedged herself in the corner with the phone in one hand and the card with the thing on it in the other, hit the button and off she went.
She actually managed to do the entire thing perfectly, not a hitch, and hung the phone up with a big sigh of relief.
Almost immediately it buzzed, so she picked it up.
"Sharron, that was absolutely excellent! We enjoyed it immensely up here on the flight deck. Would you like to do it for the passengers now?"
As for my own prowess, I'm saying nuffink.
