I recall a wet and stormy night around 1996 or 7. Full day at office, then drive to LHR for Orly on an evening BA 767. There was a problem that closed one runway so everything delayed. Because they were hoping to get clearance any minute - no refreshments served, not even to us in Biz. Happily, bitter experience meant that I had a bottle of water and some oat/fruit bars. I also had my laptop. I was OK.
Later they combined two flights into one as we were not full and we were sent to CDG as ORY would be closed for the night. At CDG we were bussed to ORY (where I was booked into an airport hotel). The drive round the Boulevard Périphérique was fine - as long as you did not look out of the window and consider the speed of the bus in drenching rain ... Hotel, snacked and refreshed by the mini-bar i slept at about 02:00.
Got to the client for 09:00 and they said, "What are you doing here today?" Turns out someone had blundered. After a quick meeting, I was promised that I would be paid for the day. I did some shopping and caught an earlier flight home.
