Knowledge is power

I rolled up to Colonial Laundromat. From Bubble-Up car wash, I hear a voice. He's talking to me in rapid-fire fashion. Shades of the Midway. Step right up. Something about $15, wash and wax and polish your car, $20 inside and out, while you do your laundry, $50. Hunh? I walk up to him. One five or five oh? I ask. One five, he says. Twenty, inside and outside. I have to go up the hill, I tell him. Which I do once I start my wash. I come back. I go for it. Inside and out. What's your name? Knowledge, he says. You should have a T-shirt that says Knowledge is power. I take him up on it. This entrepreneur with a bit of the showman and the entertainer. Philosopher, too. You gotta love what you do, he sings out as he makes some change at the laundromat. As I dry my clothes, and he does my car.
