“If I find out that my blind date with the great personality is Charlize Theron, you think I’m saving anything for the second date?”

That would be the only strategy with a possibility of success, Bob, if you knew she was dating a hunk like me the next night:
You’d have to allude to all the goodies you might provide in the future that she would miss out on if she were to go with her emotions w/anyone else, (me) and dropped you like a cold fish.

You could pick up pointers for good lines from the millions of ludicrous promises based on nothing, being bandied about in the run-up to this election.
