I want to know the answer to the following question:
What is it called when the owner of a pub allows patrons to remain when the pub should have closed?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: yes
