Who spent a lot for the wedding according to the conversation?

M: I hear that Dorthy’s folks paid a lot for the wedding.
W: Yeah! Her dad is really loaded. You should have seen all the guests!
M: Mostly from the bride’s side.

M: My goodness, Ellen! You’ve got enough groceries there to feed an army!
W: Actually, you wouldn’t believe how much we saved by using all those coupons I collected from the Sunday paper and magzines.
M: I must admit you’ve made a believer out of me. I sincerely apologize for having asked you to stop collecting what I thought was a bunch of junk mail.
