You just got to the mess hall for lunch like everyday and after getting your plate and looking for a seat you realize the seat you're used to take has something on it. It's a jacket. You pick it up confused and look for anything to give you a hint of who it belongs to - that's when you see a small tag inside it's pocket. It has a very bad handwriting in Russian but you manage to read it: Nikto.

You probably should take it back to him.
