We all have stories about bad first dates. I had an online dating experience with a lady who had posted pictures from 10 years/100 pounds ago. Another date invited me to spend the night at her apartment and I was missing $100 from my wallet the next morning; she blamed it on her roommate, but I never met the phantom roommate. And, of course, I have had one or two first dates on which the lady spent most of her time talking about her recent ex. Needless to say, those ladies did not advance beyond the first round of the competition.
So. . . what is is that a guy absolutely should not do on a first date with you? What is it that will have you walking out and taking a taxi home rather than finishing that deluxe first date dinner?
