As would I, but...Well... if I was going to get delayed for several hours, I'd much rather it be on the Sleeper than an ordinary train - at least I'd be able to lie down comfortably...
A train fault (in Mark 3 days) caused the northbound Highlander to be curtailed at Edinburgh, where we were permitted to sleep on until 6am, whereupon we were decanted into taxis for the remaining journey. We were explicitly not permitted back on the train (which was heading for Inverness, the stabling point back then) as the crew were out of hours, which is of course the inevitable corollary of several hours' delay.
