A saleswoman is driving home in Northern Arizona when she sees an Indian woman hitchhiking. Since the trip had been long and quiet, she stops the car, and the Indian woman gets in. After a bit of small talk, the Indian woman notices a brown bag on the front seat.
"What's in the bag?", she asks.
"It's a bottle of wine. I got it for my husband", says the saleswoman.
The Indian woman is silent for a while, and then she says, "Good trade."
