This just happened to me and my husband about an hour ago. We are both 30 years old. I had forgotten my wallet at home. We currently live in Iowa which allows parents to serve their children. The cashier and the manager told us that it was because of third party sales to minors. We are still fuming mad! I even was getting ready to leave so that he could make the purchase but they said they still would not sell it to him. They also said it was because it is a college town, however, we are originally from a college town that has no problems with selling alcohol to parties where not everyone has ID's. I even asked if it was a policy or if it was a law and was told it was a policy. We do most of our shopping at Wal-Mart but have started to rethink this. I have read a similiar blog to this and apparently this stupid policy has made the rounds to several Wal-Marts. If they have policies where it is harder for people to make legal purchases but the store a few blocks down doesn't, who are they potecting? I have worked for an attorney in the past and I really doubt they would not be liable by law for third party sales.
