Seem to recall seeing something similar in action in Germany that poured six of these motherhumpers at once.
You get the impression though that the staff would still find a way to completely arse it up.
On another note you can't help fail to be impressed with the way US concessions at stadia are set up. Looked more like a shopping mall food court than a basketball stadium. Brilliant.
Now where's that KFC concession you promised Tony? BARBEROUT
