They look quite cool, and it's one of a number of speedy beer pouring devices available. It wont work at the SFS though, what we really need is semi competent bar staff and bar managers who give a shit.
Have one person whose role is to separate plastic cups, another two who do nothing but pour beer, a fourth who takes the money and a fifth who floats - keeping cups and fridges stocked, drip trays empty, bars dry etc.
Then give security an uppercut. I've been legally allowed to drink for 16 years, you don't need to see my ID!
