No one here ever been to a Nascar Cafe?

This is just what they have in the bar area. Although here locally it's limited to four big screens that are preset to a specific channel. The patron can have a box the size of a napkin holder at the table which allows for selection of sound source, and volume control (at their box).

Of course, with the level of background noise in the room, these boxes are pretty dang useless, since the volume level on them has to be limited.
