Query: What is it called when the owner of a pub allows patrons to remain when the pub should have closed?
Context: A "lock-in" is when a pub owner lets drinkers stay in the pub after the legal closing time, on the theory that once the doors are locked, it becomes a private party rather than a pub. Patrons may put money behind the bar before official closing time, and redeem their drinks during the lock-in so no drinks are technically sold after closing time.
