I think being constantly on the “road” (so to speak) for long periods of time is enough to make anyone a bit punchy.
I remember hearing a story years ago about an air marshal who woke up in the middle of the night in his hotel room. Not only did he not know what city he was in, he didn’t even know what country he was in.
It wasn’t until he got up out of bed, turned on the light, and opened the desk drawer did he realize he was in Madrid, Spain (thanks to the hotel’s stationery).
ANYBODY who has travelled a lot has that experience. More than once I’ve woken up and tried to figure out where I was.
