Have you ever done something that could be considered a good deed,

then afterward wondered what the hell was i thinking?
At Costco today, getting gas, when I noticed a young person at the pumps in front of me. Didn't pay them much attention at first, pumped my gas and waited for them to finish so I could pull out (it was really busy and every pump was in use, so had to wait for the vehicle ahead to pull out). That's when I realized they seemed to be having an issue with paying. They pulled out several cards, and none seemed to work. I asked them, Do you want me to pay for your gas? They turned a startled face to me and said would you? It's reading my costco card fine, but doesn't seem to like my cards. And I just used them somewhere else with no problem.
I said sure, got out of my car, let them put in their Costco card, then used my card to pay. They politely turned away as I put in my number, and I used my other hand to cover the numbers I was pressing. They thanked me, I told them not to worry about, they could pay it forward to someone else. I got in my car and drove off (other pumps had no one in front of them for the moment), then wondered what the hell was i thinking? All i know is in the moment, I could not bear to see someone maybe down to their last dregs of gas not be able to get home.
Hope they got home safely, and wish them well.
