Makro Montague Gardens - Boorish Security at Main Gate

I visit Makro Montague Gardens on a regular basis, almost daily. On Wednesday, 2021/0113, the Security Guard at the main gate approched me in a very rude manner. It was about 10 minutes before the store was about to close and upon entering at the gate on foot, the security shouted at me 'Hey! The shop is closed' I simply said I know and continued walking. He continued talking, but I simply ignored him. I was there very close to closing time, but somebody had done my purchases and I was just meeting that person who had been waiting in a parked vehicle outside to proceed home. The gates were still open and I did not transgress in any way. I think Makro should ensure that their security staff is briefed on how to address patrons in an amicable manner. I do not appreciate being shouted at by a complete stranger who obviously is not concerned with or has no knowledge of ethical or socially acceptable behaviour.
