I held out a $5 donation and then...

I was just in the nearby shopping mall and saw a table where they wrap gifts and the money goes to charity. Where I came from, the local high school band used to do this. So out of habit, i started pulling out a $5 dollar bill... then looked at their sign and saw that the donation goes to a local Pentacostal Church. The bill went back into my wallet and I said that I might come back if I bought something to wrap.

This is an example of my conflict avoiding response to such things. They did NOT reach out to me, so I have no issue with the nice people behind the table. But - should I have told them I was not going to be back and why?
