Step on it

“Take me to the airport,” said the businessman. “And step on it.”
I looked at the businessman and put my tongs down on my hot dog cart.
“Um, I’m not a cab driver,” I said. “I sell hot dogs. Would you like a hot dog?”
“No,” he said. “I want to go to the airport.”
He handed me a hundred. “And step on it.”
So, I told him to climb on, and I peddled it as fast as I could to the airport.
He made his flight, thank God.
And I sold out of hot dogs at the airport, too!
