If I ever go on a train or bus, I put my stuff next to me, is it a major problem? No
if someone wants to sit down all they have to do is grab my attention and I will move it for them. I wouldn't want some tosser moving my handbag away from me and giving it to me. Op is just being rude, just ask and problem is solved.
Unless you are a smelly drunk then I will ignore your request for me to move my bag
