Such bad service!!

I went in to McDonalds Goodwood (Voortrekker Road, Cape Town) and was refused service because my R100 note had a tear in it. It was still one note but I was told by the cashier that she didn't have sellotape. She then calls the Manager who says to me that the machine at the end of the night won't take a torn note. So my questions are: 1) McDonalds makes so much money per hour, why can't they buy stationery for their store? 2): Why can't they use a calculator to add R100 on to the final count at the end of the night - because clearly this would be an issue if the machine can't count it so why would the Manager be able to? It's simple maths!!! Who are you employing at Management? Or are they just too lazy?
