When I was 15 years old I pumped gas at a garage. This old gal came in driving a Toad and when I checked her oil, it was all engine. I didn't know the difference between a small block or a big block, but it took up the entire engine bay.
One time she came in for gas when I wasn't working and told the attendant she would come back when I got into work. I suppose that was my first time getting a response from flirting, lol.
