Givng but not Getting

A couple months ago I received a call from someone I didn't know, but they used the name of someone I did.  This new person we'll call Herb, wanted to schedule an appointment with me.  I very carefully explained that I was not interested in what he was selling, but that I would be happy to meet to see if there might be a way I could help.

The day of the appointment he was very appropriate and likable.  I could think of several of my acquaintences that would be good connections  for him.  I have since taken my time to make those personal introductions happen, three different times.

Also, I happened to meet another new person, let's call her Sally, who would benefit from meeting Herb, so I asked Herb to come to a networking event where Sally was going to be.  Herb agreed.  At the last minute Herb bowed out.  "Something had come up."  Herb also asked me to save him a seat in a preview that we give of our course, which is basically two free hours of training. I'm sure you've guessed it, last minute, "Oh gosh darn, something has come up."

While I meet new people with no expectation, when I go the extra mile to help them, I expect that they will want to enter into the concept of giving back to others, too. 

Is this too much to ask?
