A man was walking though a town in mid-december when he saw a sign on a pub door, which read:

Not taking Christmas bookings. This pub is a Christmas Free Zone”

He walked in, and said to the barman:
“Don’t you think you should get into the Christmas Spirit?”
“I leave that to my customers. Mostly they go for the scotch, though”
“I mean, shouldn’t you be celebrating the Season?”
“Not really. See this bar?” the barman knocked on the surface in front of him. “Touch it”
The man did.
“It’s all sticky” he said, unsuprised. This was a pub, after all.
“Lick it” said the barman
“I’d rather not”
“Don’t worry, it’s safe”
The man did.
“Mmmmm.” he said. “Minty. What is it?”
The barman leant on the black and white striped surface in front of him.

“Bar Humbug” he said.
