Several years ago a Liberal friend of mine, of all people, introduced me to a bar in DC called “Red Line”. It’s across from the Verizon Center.
It’s schtic is self-serve beer. Each booth has two taps that are hooked into a table-mounted tablet that monitors how much beer is dispensed. Very neat, very automated.
He got ticked off when I only tipped the wait staff on the cost of the food. Told him that they should be thankful since the next step would be to automate that (as Applebees and Chilis are now doing) and they’d be luck you keep their jobs.
The food could be delivered by miniature train to your booth... call it the Willie Green Express...
