What are the difference between Russian service and American service?

Well in some manner they are almost the same in service they follow the same sequence from preparing all the food in the kitchen including garnishing and served by a Food and Beverage Attendant, Except their serving process is different the russian serves all food in left side of the guest carrying tray on its right hand to avoid blocking to guest always take note not to turn your back to the guest side. Beverage is served on the right side of the guest using your left hand it is practiced to make for guest convenient. Please be guided that both service use platter service.
