I am sorely tempted to find out how the bar staff in DaVinci's would react if I asked for a Giraffe.
Even more tempting is the idea of making a friend do it i.e. next time someone offers to buy me a drink. Except of course I'd probably find myself excluded from future 'rounds'.... But that's a small price to pay for the entertainment methinks.
Nia: they'd look at you blankly, pull an overly fizzy, underchilled pint of guinness, charge you the wrong amount and gawp when you tried to put them right; all whilst rocking gently to the sounds of the heavy death rock metal death metal heavy heavy rock in the background.
