This notice is stenciled on the wall of one of my favorite local joints on 3rd Street, Sinkor, where I go on Fridays sometimes. The Club Beer is cold, and the music is loud. There is even wait service at the tables. But they do have this policy. It isn't the only example around town, a lot of local bars and restaurants have signs like this, but I like the phrasing of this one. In fact, I love this sign so much that I had a copy made.
