Selective application of law undermining lockdown efforts in SA

Local spaza shops in Tembisa close at 6pm. I interfaced with one of the foreign shopkeepers and asked why he closed early, and he said that the police are moving around advising them to close at 6pm or else they will be arrested or even pay a fine of up to 10000 rands. He said that one of the foreign national shop keepers already paid 10000 rands fine. However, he also said that there are some South African citizens who do not close at the stipulated time which is 6pm and whenever the police move around the person give money to the police.
