Bartender Call Lights
When the joint is jumping, it can be tough to get a bartender’s attention (even if you’re a regular patron!). I propose each seat location around the bar have an associated light positioned on the edge of the bar top facing the server side. The patron could press a button in order to trigger the light, assuring the bartender will see the light and save the waving arms and fruitless shouts across the noisy room trying to get the bartender’s attention.
These would function similarly to the attendant call lights on airplanes. The light stays lit until the bartender comes over and turns it off when taking the customer’s drink order.
