Rude Manager and Staff members

I went to Clicks Denlynne to get some meds @ 16:42 and met the manager(Lucky Masemola) at the door, he was attending to the other customer when I got in and it seems like he was preparing to close the store. One of the staff called him to look out at the door as its approaching time to close the store. The manager rudely asked me to leave his store as the store is closed ,I then asked him what time do u close the store because the door is still open he said 17:00 I told him to take a look at his time because mine says 16:44, he shouted at me asking me to leave his store. I told him to ask me nicely not rudely since I'm younger than him. He didn't even his staff were screaming that they wanna go home it's late. I left the store disappointed and sad. I'm never visiting that store rather go to the next complex if not another store than clicks.
