Quote from Blanche in The Actor
Blanche: Who's the flower for? Rose: Oh, it's for Patrick. I thought I'd give him a rose for good luck since it's opening night. Blanche: I'll give it to him. Rose: Why should you give it to him? Blanche: Well, haven't you heard that old theatrical saying? Rose: No. Blanche: Never accept a rose from somebody named Rose on opening night.
