It is an anomaly IME, but maybe in SA drivers are less courteous or less skilled? And i did comment on the fool who parked over the line in your photo.
Although here someone would report them via the Snap, Send, Solve app. Police will issue fines from photos if someone is parked illegally *i.e. in a loading zone); and the community face book page is very good at shaming selfish cough who take up more than one spot etc.
Í could easily post weekly photos to show you how normal it is where I live for most to reverse park properly leaving plenty space to maneuver trolley to the boot and safely exit the car park. But nothing is ever going to convince those who can only manage to drive in that there isnt a better way.
Also interesting you choose to only attack my posts when plenty of others have mentioned the benefits and preference for reverse parking.
And at my local bunnings the tradies have a separate entrance and pick-up (Bunnings Trade) vs retail which has both a click and collect pick-up area and also a loading zone for bulky/heavy items bought in store. YMMV if you have a small Bunnings, but again delivery is always the easiest.
