What does Tom invite Betty to do?

M: Hello, Betty, Are you free this Sunday? How about going to see a film with me, or a play?
W: Tom, I’d rather see a play. I hear a new play is on at the Grand Theatre.
M: Good. I’ll see if I can get tickets for Sunday.
W: On Sunday there’re always so many people there, How about Friday or Saturday?
M: OK. I’ll give you a call about the tickets later. Goodbye!
