Final answer:
The bouncer working outside an alcohol establishment may need to be certified depending on local regulations.
Step-by-step explanation:
The bouncer working outside the entrance of an alcohol establishment has the primary responsibility to control the number of patrons entering and to check their IDs. Whether the bouncer needs to be certified or not depends on the local regulations.
In some jurisdictions, bouncers or security personnel working at alcohol establishments are required to obtain certification. This is usually done to ensure they are trained in dealing with any potential issues that may arise, such as handling intoxicated patrons or defusing conflicts.
Hence, the correct answer would be yes, because all employees of an alcohol establishment must be certified.
