Suspicious behaviour at Domestic Departure Security.

The security supervisor at Domestic Departures on shift at 13:55 was rude and aggressive, when I was being a Good Samaritan. I found a bag someone had forgotten after the metal detectors. I could see there was a telephone number on the tag. I tried to get the number to call the passenger (who I didn’t know) and the bald headed man in ACSA blazer who said he was the security supervisor told me to mind my own business! Why wouldn’t he try and help? He could’ve easily let me contact the poor customer who forgot their bag at the metal detectors, but was adamant I didn’t. He said “just leave it and mind your own business” Probably because he wanted the passenger to leave his bag at the airport so he could ***** what was inside! Is this how we want people to treat each other….I’m sure if you forgot your bag at an Airport you’d want someone to help?
