I am too, and I think most guys are about most things like this.
When guys say, "Whatever you think is fine with me." , "Anything's good", "Whatever you'd like" we mean exactly that.
So going back to the comic, if Blondie just walked in and said, "We're having hot dogs for dinner" and there is a 99% chance that Dagwood simply says, "Sounds good to me" why go through the song and dance of fake options?
