Toots re your story about the auditorium: during our 2005 trip to the UK we went to "The Mousetrap" at the ? theatre in London. Fabulous and the tiny theatre was wonderful! Fortunately I hadn't had my snout in the trough beforehand but I remember being amazed that you could not only get a drink at intermission (not always the case here) but you could take it back to your seat!
I'm glad those days are over.
