Salesman

A salesman is driving toward home in northern Ontario when he sees an Indian thumbing for a ride on the side of the road. As the trip had been long and quiet, he stops the car and the Indian gets in. After a bit of small talk, the Indian notices a brown bag on the front seat. "What's in bag?", the Indian asks the driver. The driver says, "It's a bottle of wine. I got it for my wife." The Indian is silent for a moment then says, "Good trade."
