And I think Mr (not Inspector) Sands is standard code in theatres and
cinemas for "there's a fire". He gets everywhere!

I heard an odd announcement on a GNER train the other day "There's a
chicken tikka ready in the buffet, I repeat There's a chicken tikka
ready in the buffet". What does that mean? I didn't realise GNER sold
chicken tikka's. So it must be code for something!
