What does the "one-way door restriction" imply?

The "one-way door restriction" refers specifically to a policy that prohibits new customers from entering a venue after a designated time. This policy is often implemented in establishments that serve alcohol, particularly to manage the flow of patrons as closing time approaches and to ensure that management can maintain control over the environment and the number of individuals present inside. By allowing only exiting and not permitting further entries, the establishment can more easily enforce safety, manage crowd control, and ensure that all customers are accounted for as closing time nears.

This practice is particularly useful during busy nights or events, where maintaining a manageable number of patrons is crucial for both safety and compliance with local laws.
