Good Trade

A traveling saleswoman is driving toward home in Arizona when she sees an Indian woman hitchhiking. 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".

The Indian woman is silent for a while, then nods and says,
"you made a good trade".
