The place my wife and I used to play out of had 3-cue Cue Claws screwed down to every table and shelf in the place. They (the cue holders) were used on a regular basis.I carry one that holds 3 cues and that thing is pretty heavy. I already have a heavy case too.
What they DIDN'T have was a single coat hook in the entire place. In the colder months people either left their coats on or tried to find an empty chair to hang them on. Coat hooks along the walls (or underneath shelves) are also a good place to hang up a cue case. And...they're inexpensive.
