We are from Australia and treat everyone with courtesy and respect.
The waiter in the morning Breakfast Room was very rude. Can't remember his name. Starte with Y. Tall guy, with a beard, white shirt and black trousers. The coffee machine was not working and the coffee was not hot. So I requested him to make it hot. He said he will do it only for one day but never again. The next day I had the same problem. When I requested him he rudely said NO. It did not take him more than 2 minutes to warm the coffee. But very rude and unhelpful.
