Why at movie theaters one employee is usually responsible for issuing tickets and collecting cash while another person collects those when patrons enter into the theater?

Separation of duties, security, fraud deterrence: This separation helps prevent fraud and errors by ensuring that one person doesn't solely handle money at movie theaters. Collecting tickets after people enter the theater ensures proper admissions management and ensures no unauthorized entries.

Handling peak times efficiently: During high-traffic periods, having distinct roles can manage large crowds to issue tickets quickly and facilitate smoother entrances to keep movie-going experiences efficient and satisfying.

Compliance, regulatory issues: In some jurisdictions, local regulations for cinemas and theaters may require this specific setup for handling tickets and payments to stay compliant with legal mandates.
