After you get your date back to your place, and you haven’t closed the deal to have her spend the night, you ask this question: “Would you like your scrambled eggs with bacon?”
The idea is to get your date thinking about a decision that would come AFTER the decision to stay the night. It’s a standard sales technique, also known as getting your buyer to think past the sale. You want the prospect to imagine where he would ride that motorcycle, not whether he should buy it in the first place.
