SOUR MILKSHAKE

While waiting for a MRI Scan report, I went to Vereenigning Medi Cafe to pass the time. Ordered one of their 'new items' on the menu, a Bar One Milkshake. As I started drinking it, I realised that it was completely sour. I always have milkshake everywhere I go, so I do know what it generally should taste like. Without making a scene or being impolite, I kindly informed the waiter that the milkshake was sour and that I would buy something else instead. The owner came over to me and very rudely explained that she differs from me and that the milkshake is definitely not sure as she tasted it and she only uses long life milk and made me pay for it. I did not want to make a scene, so I paid for it. Just because you use long life milk does NOT mean it is fresh.
