You walk through number 8 and find yourself right back in the pub, at the main entrance. Everything is the same as a moment before. In the back, by the washroom, you can see the same sideway 8 door you entered through to reach the hall in the first place. A loop . . . of some sort.
Disorientated but relieved to be safe, I make a note of number 8. I notice some other patrons are missing and wonder if I'm being too risky.
But curiosity has taken hold so I head back towards the corridor with the intention of walking much farther this time to see if I can find door number 1979.
