Does bad dating Karma exist?

To reschedule with one should I cancel with someone else?  Would this give me bad dating karma?  I do believe what goes around comes around....but am I missing an opportunity?

So bright and early this morning I get a text message - it can't be a guy it's too early, they only text late at night right?  Well it is Bill (aka: cancellation guy) and he wants to meet up tonight at our previously arranged spot.  Doesn't it figure that this was the one night I have a date - my back up date to his cancellation to be exact.  I tell him this is the only night I am unavailable this week and ask if we can reschedule.  No can do as he has plans to visit his family over the weekend and guess what? I work nights next week and then go to Florida - our schedules are not blending well.  He did write "We'll make it happen soon". Maybe....

My first thought when I got his message was to cancel with tonight's date. I am more interested in cancellation guy and the other one hasn't even gotten a nickname yet....but I am afraid of bad karma. I could probably reschedule for tomorrow and have back to back dates and get a first hand look at both...but I am afraid of bad karma.

F@#% Karma
