Duff Vendor

The Duff Vendor runs a stand selling alcohol-free Duff Beer at the U.S. Air Force Base's airshow. Homer Simpson notices the stand, but people are standing in front of much of the text and he thinks it merely says "free Duff" instead of "alcohol-free Duff $6". He has already drank several cups by the time he recognizes his mistake, so he sneakily exits the scene.
