In my thinking, should the questions be asked, "Could I call you again?" or "There's something I think you'd enjoy going to next Tuesday night...blah, blah, blah." then you have your cue to say, "I had had such high hopes for our date tonight. I wish things could have gone differently. But unfortunately I didn't enjoy it as much as I had wanted. I thank you for thinking to ask me to join you tonight but I would prefer that this be our last date.

If this invokes either pleading or gnashing of teeth, you say "I am sorry. This is how I feel and it is not open to further discussion. Goodnight."

Well, at least that is how I remember it when I was on the receiving end...*G*
