A door supervisor, commonly referred to as a bouncer, is a security expert tasked with overseeing access and maintaining order at the entrances of establishments like bars, clubs, restaurants, and events. Their main responsibilities encompass verifying identification, checking tickets, regulating the flow of individuals in and out, and safeguarding the well-being of guests.

Door supervisors are charged with deterring unruly conduct, mediating disputes, and managing crowd dynamics. They receive training to address a range of security challenges, including potential threats or emergencies, and are essential in fostering a secure atmosphere for both patrons and employees.
