If you're an actor you might say 'I don't do movies, I work in theatre, darling!'
Is there a reason why 'I work in theatre' (as in the theatre industry) is incorrect? I thought that 'theatr' meant either 'theatre' or 'a theatre'...
'I work in a theatre as a box office clerk/stage manager/cleaner...'
' I work in theatre' = I'm an actor
I work in A theatre!
