In terms of the pay the security officers receive, it is not expensive at all. Unarmed security officers typically are paid just above minimum wage per hour. Armed make only a dollar more per hour. I know from personal experience as a security officer in Los Angeles during the 2008 recession, and today in Charlotte, my roommate makes only $14 an hour as an armed guard. Their last raise was 8 cents an hour. I am not kidding. The security companies might get lucrative contracts, but they don’t pay their employees well at all.
The only way would be to scream them before you let them in like at a night club..
