Final answer:
Professional Security Guards should indeed enforce site rules and regulations, but they must do so professionally and respectfully.
Step-by-step explanation:
A good characteristic of a Professional Security Guard is to enforce the rules and regulations of the site they are tasked with protecting. The assertion that they should indeed demand compliance if site rules are not being adhered to is accurate. However, how they demand compliance is crucial; it should be carried out in a professional, courteous, and lawful manner. Professional Security Guards should provide clear instructions and explain the reasons why compliance is necessary, ensuring that their actions are both appropriate and respectful to individuals involved.
