Salad Dessert Forks

What are the uses of many spoons and forks on the dining tables in hotels?
I feel that spoons, forks and knives are too much in dining tables in hotels. Ok, one can be for salad, one for the main course and one for desserts. But still the number seems to be more than we need. And also, Is there a special spoon for soups?
