MANY years ago working with Air UK on F27 CDG NCL. We had the David Sanborn band (famous saxophonist) on board.
Mr. Sanborn went to the loo and seemed to disappear for quite a while.
Eventually this sheepish face peered from behind the partly open door: "Em, where's the flush?"
Me: " Don't have one, it's a chemical toilet Mr. Sanborn."
pax: " So, where does all the s**t go?"
At which point I just burst out laughing, and eventually so did he...but you know!?
More recently, last year pre SEP 11 I did a private flight with some VIPs who were distraught as there was a possibility that we could not land at the destination. At which point they demanded to go to an alternate, which the flight deck did not have the plates for...the answer "It's okay we will direct him!"
The flight was dodgy enough without this suggestion! DOH-KDH...but we got back!
