Haha don't get me wrong at the time groggy eyed and pee'd off I could feel very tempted to do that, I appreciate your advice but Im not going down the criminal damage route, the landlord would foot the bill and it's not really his fault plus it's just not something I would ever do.
I'd love to give the lad a good hiding too but again it's not the way forward really, I won't be in this situation for months or years as I'm free to leave here if I'm feeling threatened or unhappy I just mentioned it is financially beneficial to stay put.
