security personnel very arrogant, unprofessional, not sympathetic and bullying

Cape Town airport security personnel very arrogant, unprofessional, not sympathetic and bullying. I brought my wife and 2 kids to airport Saturday morning 20 Feb and while my wife was on que I then took her luggage for check in. On my return to the door I see its return no exit. I explained to the office and he refused said I must walk 5kms to my car which is opposite to the door at drop off to fetch my kids.
