Bad customer service

Firstly the lady gave me R8 change instead of R8,29 and no decency to say we don't have coins but I understood? I bought chocolate milk shake and was given Vanilla I address it the lady just pours a small potion in a different cup and says it's the same. I don't care if it's the same or not I bought chocolate milkshake even looking at this you can tell it's vanilla... burger King Braamfontein just had to ruin my day
