Based on the case what is the most probable cause of the performance problem:

Question $28$ options:

Employees are having trouble estimating the age of customers because they are now wearing masks that cover a significant portion of their facial features.

Employees are avoiding asking customers for their ID because they don't want to deal with the conflict if someone doesn't want to bring their ID$.$

Employees are paid by how many customer sales they make, so they don't want to take the time to assess every customer's ID$.$

Employees don't know what the policies are and are not clear on what is expected of them, so only employees who are more senior ID people.
