I ha have a Kathrine Hepburn a memory Back in the 70s she was doing a play called "A Matter of Gravity." She played lesbian nun as I remember. Anyway, a couple came in late and made a big commotion about finding their seats. It was distracting and annoying.
Kate pulled herself up majestically and said tot he couple "Let me know when you're done and then I shall continue"
She got a standing ovation 30 minutes into the play!
