How wrong can I be?

I keep thinking about an incident that happened during December's First Friday.  Our store was full of people looking at jewelry, visiting, drinking wine and eating.  I noticed a young man, very casually dressed, who came in by himself.  He's here for free wine and looks underage, I thought, so I kept my eye on him.  He walked past the jewelry displays, past the food and drink, and back to the cash wrap.  I watched as he pulled out his wallet and stuffed bills into the can for donations to the local food bank.  Then he left.  He wasn't here to get something for nothing, he was here to give something for nothing.  Snap judgments can be so wrong!
