When I was 16, I took my old beater to get some gas at a gas station. I pre-paid for my gas in cash, but with a large bill. When I walked out I noticed that the store clerk gave me $20 more than he was supposed to. The two $20 bills just stuck together, I suppose.

I brought the cash back to the clerk. He thanked me and asked me if I smoked. "Yes, I smoke" I replied. From then on until I was 18 he would sell me smokes when I came in, along with other employees that worked there. Years later I met him again randomly at a bar and he bought me a few beers.
