Yeah, I totally agree Ganbare,
But just to put it in more of a reality situation,
I recall enjoying a day off in Paris, at the airport hotel, when I got a phone call to catch a flight to Manchester, a change of basing, but I didn't quite have enough time to take a shower and be able to make the departure time!
Changes in basing were something that could occur at any time, without much notice at all.
Thats what it was like, all the time!
