I don't deserve customer service because I am a student... ****ty attitude by Pick 'n Pay Supervisor

So on the 28th of June 2021, I was at the store around 11:20am joined the queue to make my payment and also request for a cash back of R500. I then got to the caisher I made the payment fof the things I was purchasing and after I asked for the withdrawal and the Cashier responded to me " we do not have money, we all started to work at 11H00am, so there is no money." I was very puzzled and at that time it's already 11H50am so I asked "do you suggest thar I leave because you guys don't have money as a whole store?" the cashier's name is Khumbuzile Jiya. She then proceeede to call her supervisor who really ****ed me off instead of being helpful. Her name is Thabi (Thabisile) D. So when the supervisor got to she says " Uthini? " and I responded" what do you mean by saying ngithini? "... She started giving me attitude saying the whole store doesn't have money without trying to ask other cashiers if they have accumulated some cash. She told me that I shouldn't" phaphela". I had an intellicard (NSFAS) on my hand with I was gonna use for the withdrawal she said "plus you are a student, you can withdraw R100 from 5 cashiers then I will have my money". I've never felt so disrespected this clearly showed me that they weigh people according to their looks, age and what they think you worth so since I am a student I should go pillar to post for me to be able to get cash. I asked for the manager, he came through just didn't get his name I really did not like how he actually handled this matter but atleast he managed to assist me and he placed my needs first. Surprisingly the manage got me the R500 from the same cashiers who were on duty when I was told no one has money. When I asked for an apology from Thabi D, she laughed and said "apology from me, never" and she walked away.

This is Pick 'n Pay in Dobsonville opposite BP garage. I was so angry and am still angry at that supervisor. I felt like beating her up but I known that will result into an assault but I need the manager to seriously attend to such matters because if a supervisor can be so rude to customers then we will be always served with ****ty customers service by their Cashiers. They must review their customer service standards and also provide training.

As for Thabi next time I won't let her get away so nicely and I I I am watching her.

Thank you
