Has anyone seen this before? A table with a series of fonts built in over drip trays with kegs stored below in the base. The idea is to serve your own drinks with meters built in showing how much you've had. I spotted this in The Cross Keys in Chelsea yesterday, it's not up and running yet but just been installed.

Not sure about it to be honest, plus how do the staff ensure people don't leave without paying?
