Auditor Trap
Inspired by a photograph of an Oriental food shop boasting "Thai Cuisine And Sushi Bar". The Ankh-Morpork times - News of the Disc page on Facebook has a collection of these, seemingly baffling, internally contradictory and illogical things which we take for everyday, but on closer examination appear designed to trip up the ultra-logical Auditors of Reality should they come calling.
The Auditor gestured, and a map of the Counterweight Continent opened up in the air in front of them. His two fellows crowded in to look, and the three grey robes somehow seemed to radiate a sense of existential perplexity.
"But BhangbhangDuc is here. On the peninsular isthmus to the Widdershins and the islands extending it to the sea. But not so Widdershins as to be the Grimchi Peninsular."
"Meanwhile, the region of Agatea that favours sticky rice and miscellaneous seafood bound in rolled fibrous seaweed is here. Nearly a thousand miles away."
"Why should ANY human choose to consume sticky rice and miscellaneous seafood bound in matted rolled fibrous seaweed?" a third Auditor asked. "Or indeed cabbage marinaded in vinegar and buried in soft earth for a year?"
The first auditor frowned, insofar as emptiness shaped by a hooded grey robe can frown.
"But even so. If sushi is found here. And BhangBhangDuc is here. Then logically, this restaurant must, on the inside, occupy a floor space of at least a thousand miles."
The three Auditors considered this.
"The waiters must be fit. And fast." one observed.
"Bigger on the inside than the outside suggests..."
"Oh, it's a bloody Tardis." another Auditor said. "Time Lords taking the piss. I hate those things..."
The two remaining Auditors looked at each other.
"I hope those waitresses get good tips, all the moving around they've got to do..."
And then there was one, waiting for two new fellows to pop into existence.
