January is National Brain Teaser Month! What Question Do You Ask?

January is National Brain Teaser Month and I love brain teasers!  Here’s what we are going to.  I’ll post a different brain teaser 3 times a week, if you think you know the answer, leave it in the comments.  I’d love to see how smart my readers are!

A shopper comes to a fork in the road which leads to two Walmarts. In one Walmart the associates always tell lies, and in the other Walmart the associates always tell the truth. The shopper needs to buy groceries in the Walmart where everyone tells the truth. An associate from one of the Walmarts is standing in the middle of the fork, but there is no indication of which Walmart he is from. The shopper approaches the associate and asks him one question. From the associate’s answer, he knows which road to follow. What did the shopper ask?

Stumped?  Here is the answer.
