Unhygenic Behaviour

On 25th May while waiting for my order at the drive through collection window it was with disgust watching an employee take a personal juice bottle and fill it up from the coke machine . Not so much that she was taking about 1L of coke but the fact that the part you drink from on the bottle was touching the nozzle used to fill up customers cups. How many people do that there and how many germs are you spreading to customer?
