Sometimes people have given me a student/senior discount, and I'm fairly young. They just did it because I was digging for change, and they were trying to either be helpful and kind, or keep me from holding up the line. XD But really, after being carded so many times at bars, I'm happy when people start seeing the aging process in me. I look at aging as a really poetic and natural process.
That said, awesomely entertaining story. You have great story-telling skills!
I had one like that, not too long ago...Went to Walmart, paid the lady, got to the truck with no bag in hand...Went back and picked it up...Drove, immediately to the Walmart gas station, walked in, handed the cashier $40, walked out, jumped in the truck and was two miles down the road, when I looked at the gas guage....What the ----. Luckily, I got back to my pump before anyone got $40 worth of free diesel fuel.
