Went to checkers Sandton city at 3:15 to buy wine and a few other things for lunch boxes, naturally I went to the wine section 1st and I asked the guy if Ill be allowed to pay since 3:30 might hit while shopping for the rest of the things I needed,he then directed to the 2 ladies at the pancake section to process the payment FOR THE WINE,There were 2 ladies there the lady on the green hair blatantly refused saying they are busy with orders they can't help me...I then said it's just 1 wine and I don't want to have to hold 2 queues she said they not allowed to touch the system when then are busy looking at the pancakes *sarcastic* ...I held my queue and went to carry on shopping and there I saw her touching the system helping the lady who was wanting to buy Cake ...isn't it double standards? Also what's the protocol cos I had the wine long before cut off time? I'm generally appalled by the service in that store ,some don't even respond when u greet them back. I'm happy not to use it just thought you might want to know the segregation going on there or staff choosing who THEY want to help and who they don't ...I didn't catch her name but she dark, small/medium size with Olive Green BRAIDS. Will go to Pnp across the road in future
