What are these two people talking about?

M: What kind of dress are you looking for?
W: Since it’s getting warmer this time of the year, I want something lightweight. What do you think would be the best?

M: I must say, Miss, the food was great and I’ve never had better service.
W: Well, thank you, sir. I’ll pass your praise on to the cook and the manager. And thanks too for the tip.
