I was annoyed with myself for drifting/dozing off during a recent Saturday evening performance of White Christmas because I'd booked the tickets months in advance and was really looking forward to it. I came to a couple of times unsure of what I'd missed (even though my friend filled me in and it wasn't much, but still...).
I made sure I went for a brisk walk round the block during intermission and bought a cold drink before returning to my seat at the very last minute. A few other people at the bar were complaining that the temperature was too high and they felt a bit drowsy - maybe it was subliminal and outdated promo by the Marquis!?
I've also dozed off at a couple of Disney shows but I put that down to them being too long and formulaic (Mary Poppins esp), so I wasn't so bothered (apart from having wasted my money obviously)!
Seen some shows in my time....
