it’s really not that simple. First, if you keep nuisance complaints, they’ll fine you (or in my case, fine my clients. which would have me fired.)
secondly, you annoy the cops enough, they’ll freeze you out regardless of what their policies/rules say, and as a security guard, you’re reliant on them to come save you if you ever have an active shooter or, more likely, just an aggressive asshole who doesn’t like being told they can’t do whatever it is they’re trying to do.
