In an attempt to make up for lost revenue universities are starting to allow beer sales inside the stadium. West Virginia is one of them and claims they claim to make $700,000 a year and have seen a decline in unruly fan behavior. One of the reasons they say is that by banning alcohol inside the stadium you force fans to binge drink outside before going into the stadium.
How does this affect BYU? We don't get this potential revenue, but we also don't have to worry about unruly fan behavior which makes us always hospitable to visiting fans.
