For the first time, I noticed they had a basket of paper bags of feed, and a sign that said, "Feed The Horses. $1.00"
I thought I would save the young driver some work. So I said, "I'll feed your horse for a dollar."
He thanked me and handed me a bag of feed.
"Where's my dollar?" I asked.
"Excuse me, sir?"
"I prefer to be paid in advance, but only because we just met."
He looked perplexed for a minute. Then he said, "Sir, you pay me a dollar."
"Why would I do that? This is your horse, isn't it?"
"Well..." He thought for a second. "Yes, but the feed costs money."
"The horse is going to eat with, or without me, isn't it?"
"Then why would I pay you a dollar to use your feed to feed your horse. I'm doing you a favor by feeding the horse so you can stand there and relax." I smiled. "I know you probably get paid more than a dollar to feed and care for the horse, but don't worry. I don't mind doing this part of your job for only a dollar. You seem like a hard-working young man, and you should get the profit from my work."
...Strangely, he decided he didn't need my help.*
*This conversation took play only in my head, not in real life. The imaginary conversation was enough. I paid myself a dollar for giving me something to laugh about as I walked to my car.
