Worst service ever

Yesterday I went to Pick n Pay , I had my 18 month old daughter and my 8 year old with me,,, I was struggling with managing to keep my eyes on my 8 year old and dealing with the baby throwing tantrums, she had an ear infection so she was not feeling too well.....so I eventually get to the check out and the cashier rings up my things ,now I need to get to my purse with my baby on my arm and my eyes on my 8 year old .....and im starting to sweat because I can see judgmental eyes on me coming from the people in the Que...... so I just I place my baby on the counter for maybe 15 seconds to get out the cash so that I can pay , and the cashier says to me Mam!!!! can you please take the baby off the counter whilst rolling his eyes......I was so Embarrassed I walked out of the store with my screaming baby .....it actually bothered me for a while and I was thinking maybe Pick n Pay staff treats you according to the area you live in ,as I dont come from an affluent area and it was Pick n Pay Mitchell's Plain but then again there is absolutely no difference in the money I pay , I think people has to have a bit more empathy and even consideration for the mother that just got out of a full day of work ,coming home to her babies ,needing to grab groceries at the store to come home and cook then clean her home and bath her kids ,doing the homework.......she gets to bed maybe around 11pm if she lucky and then jump up again at 4am to do the same thing all over again......so sorry if it seems like she doesn't have her **** together or like she is not picture perfect......sorry about venting I just feel like people should be less judgmental and Pick n Pay need to train there staff......
