Who's a Dental Hygienist?

There's a joke that goes:

An English tourist is on holiday in the Highlands, and feeling a bit thirsty he stops in at the pub in the village he's staying in. It's a pokey little place, and deserted apart from two locals in the corner who're playing chequers and conspiciously not drinking anything.
He's a bit worried that this might mean that the drinks are ridiculously pricey, sp he asks the barkeep how much a glass of whiskey costs.
"Ten pence", the barkeep replies.
He can't believe this! Ten pence? How can that be? He's never one to look a gift horse in the mouth though, and orders a glass of the nicest whiskey in the pub.
Wishing to be friendly, he asks the two locals why the spirits are so cheap. Apparently there's a big distillery nearby, but he's puzzled to notice that the locals aren't drinking anything themselves. Curious, he asks why.
"Oh, it's simple enough" one of them explains. "We're waiting for happy hour."
