Rude Supervisor/ Manager

On the 16th of August around 18H15 and 18H50 i went to Nandos to buy my full chicken, wedges, rice and green salad for supper for my family. Then we went to another grocery store while waiting for our order. When coming back i sent my 7 year old to pick the order while waiting for her at the door. The door is 5 steps away from the till. They gave the child the order. When i got home i realized that the green salad was not in the order, so i couldn't go the same day to pick it up but told myself i will go following day and it didn't cross mind that i should call and alert them. Also couldn't find the slip.

when i got there, luckily the /Supervisor/manager (lady) was in front so I told her my story. Yhoo little did i Know that i had opened myself a can of worms. The lady was so rude to me to an extent that she addressed me sitting down where clients wait for their orders. She told me that she was not sure if had been to the shop the previous night or not. And that she doesn't even know if the green salad was rang on the order or not. So she cannot validate my story. She started doing examples of Pick n Pay that you cant go to them and claim without slip. I was so annoyed but calm and ended up asking if she going to help me or not? She continued with sarcastic questions and I ended up saying because im not getting any help let me go. Ive never felt so humiliated in front of clients. My point is i would drive my car from where i stay with petrol milage and come claim for something i didn't even buy. Also my pay date was on the previous day of which i still had money or afforded to buy myself food. Maybe she looked at me the way i was dressed and decided to undermine. should it have been a white or Indian im pretty sure would have been treated differently.

I was so disappointed i must say, she made me feel like a dirty beggar not a client.
