Same here when it comes to me. I've been given grief at 21, now 23, when I was Gold Medallion for a while by people who didn't believe I had status. I've never had a problem at ATL though, only place I ever got some sort of trouble was at DCA.
Now when entering the Sky Club I've had some pax say I am going to the wrong area. All I say is I know where I'm heading and once we enter the Sky Club I've had one of them tell the lounge dragon that I was begging to be guested in...but the dragon at DCA's Sky Club knew me and welcomed me in personally. Best...feeling...ever...
