Well Sol?
You told the story, asked a question and so far, nothing more from you.
Seems to me that there are a few different viewpoints here.
Some say "Tough luck, ladies"
others "Keep the customer satisfied"
and then there's some kind of "Liberal" debate going on that has nothing at all to do with the subject at hand.
So maybe you could step in and just explain why you refused to give these two particular ladies their own donations back at this particular show.
You did know who you were hiring, right?
You knew that they were Anti Bush, right?
You warned everyone, right?
They gave a donation and changed their minds.
Beats me why you chose to respond the way you did.
