I meant to take one, but I have an iPhone 4 (!!!) with a contract expiring this summer, so even though I've deleted all non-essential apps there's not room to take a single photo . I could produce a mock-up when I'm back home...

One waitress just stopped and produced a delighted squeal, so maybe I *am* the first.

Of course, I will soon have to dispose of the ice water (salt is a nice idea, but they don't stock it in quantity - maybe I'll have to start bringing my own as well). My current plan is to chuck it in the loo.
