Be cooperative. Don't act exasperated―or act out―when a security guard asks you to do something. Instead, just follow the rules. "Understand that this person has a job to do," says Tony Dandridge, president of Dandridge & Associates, a security firm based in New York City, and a longtime corporate-security consultant. "Security is always the last to leave and the first one there." The procedures of security personnel are put in place as safeguards.
Smile and greet the guards. But always keep the relationship on a professional level, says Dandridge: "We can't let ourselves get too close. You never know when you're going to have to escort someone out of the building!"
Treat them with respect. "They're the solution," says Dandridge, "not the problem."
