Lock-ins

From Frikipedia

Fun, but illegal pub activity.

When 11pm rolls round, instead of time being called and everyone politely hustled out of the door, the curtains are drawn, the doors are bolted and service continues.

The first time you are part of a lock-in, the sight of doors being heavily secured and curtains furtively closed may lead you to the mistaken belief that you have accidentally stumbled on the final tragic meeting of an offshoot of the Heaven's Gate society. Don't panic, by being allowed to stay, you have become part of the pub family. Drinking can continue based on the unspoken rule that you tell no-one about this. Which of course you will do as soon as you get up the following day.

With the onset of 24 hour licensing laws, the days of the lock-in are numbered, seeing as now there is very little subversive in the act of staying open longer, unless you haven’t applied for a longer license. This is rather a dull and technical method of being a rebellious pub owner, and so it is usually best to just get the license.
