"It could be anything," Shannon told the television station. "Again, I have no code requirement that I can make him change anything.
"I mean, when someone brought that up and said someone could be confused to think it is an emergency clinic or a hospital-type facility, we could see that a little bit," Shannon said. "It is kind of in that gray area, so we want them to be clear."
Owners of the club have not responded to requests for comment.
