I was pretty annoyed in Riften one time. I was low level, poor and didn't have a house yet, and was carting a lot of stuff I wanted to keep around. I'd been forced to leave a lot of sellable items in a nearby dungeon. When I saw the: "Steal from empty chest" sign, I thought: "Hey, I got this place a day. I can just put all my stuff in here, go back to the dungeon, pick everything up, bring it back to Riften, profit and keep all the stuff I want!"
So yeah, Romlyn Dreth yelled: "Hey! You can't do that!" and a guard came charging in screaming: "You have committed crimes against Skyrim and her people! What say you in your defence!" Apparently in Skyrim it is illegal to put a bunch of items you legally owned into an empty chest.
But the aspect of it that REALLY annoyed me was not that I was being arrested for putting things I legally owned in an empty chest, it's that I was caught doing so. I was in the upstairs room in Riften and had shut the door. Eventually I figured out Romlyn Dreth had seen me (and thus was able to snitch on me) because he had been staring at me through the cracks in my floorboard from his usual seat in the bar. A male had been carefully watching my female PC in a bedroom at night when she thought she was alone and unobserved. Creep.
