Drunk Flap

Drunk flap is fitted to the back or side door, like a cat flap, only it's big enough for a person to go through on all fours. Particularly useful for hotels, where hard drinking guests would be offered an activation collar, so that when they crawled up the steps on their hands and knees after a heavy night, the Drunk Flap would spring open, allowing them to access an alternative, more discrete route to their room. This route would take the form of a series of low lit ducted passageways, just big enough for two people to crawl past each other on their way to nocturnal oblivion.
