How is the weather in Russia? You are an elusive one!
To address the service charge issue on the Dutch side. When 15% is added (they can call it what they want) we usually leave another 5% IF service is good, it not we go with what is on the bill.
Regarding having had BAD service when the 15% is added. Several years ago at Taloula Mango, I did ask to have the entire 15% removed due to the total lack of service. It finally was removed and I despise going back to that place.
