Let’s not jump to conclusions. The security officer on the ground doesn’t get to make the rules - their employer or “the client” does. Sometimes those rules are stupid and senseless. You still have to follow the rules and adhere to your employer’s policies.
I must admit to being somewhat impressed by this idea you have of a mall-world populated by wise, or even foolish, mall-owners and shop-management, calmly deciding the rules of their little republic, and holding evening classes in the rules and regulations for the education of the elite corps of policy operatives to be recruited via specialist employment agencies.
Are you insane?
None of these people have a clue what they’re doing. They’re bumbling along like the rest of us, reacting to things, many of them contrary to their expectations, and therefore reacting badly.
