Wrong order

Was a rand short for my order a lady who seemed like a manager said it was fine and that I shouldn't swipe for a rand... as I was waiting on my order I realised I had R8 in my jacket, coz I was happy they were considerate I give it all to the cashier. Got my order boarded the gautrain home to JHB, got home only to find my burger was not in the bag, this was on Friday 24th I am really not happy with this
