LiquorShop Closing Times

Checkers LiquorShop in Rivonia Village closed before the Covid-19 Regulations for Alert level 3. On the website and window, the operating times are shown at 10 am - 6 pm. The doors were closed at 5:40 pm with no excuse on why they were closing early. I requested to speak to the manager and had no response from anyone until after 6 pm where then Miss Govender that was the so-called manager has advised us that HQ informed all Checkers LiquorShop's to close at 5:30 pm on a Thursday, as sales after 6 pm will not be sold as they will violating the law. Can someone please advise if this is true and if so, can you please update the website and shopfront windows? Please understand that customers were rushing from work to purchase alcohol for the weekend.
