Worst Service at Buco in Kariega/Uitenhage

I had the worst experience at Buco Kariega when I was not allowed inside the store because I arrived at 16:50 and the coloured guy at the gate who refused to give me his name said they close at 16:50. He was also not wearing a name badge by the way. I asked why would they put up a 17:00 closing time on their operating hours board and he said from 16:50 the cashiers are cashing up and no one is allowed to come in the store. When I asked for their store manager he said he went home already yet after I called one of the store employees I know a manager came to talk to me moments later. The manager I spoke to (a short white guy) said they close at 16:50 because of safety and security and that is their store policy known by their head office. That time I had left work earlier to make it in time to make my purchase but that was all for nothing. I will never go back to suck atrocious treatment as a customer of this brand. Clearly closing earlier than the displayed time is more important than my purchase.
