im seriously dumbfounded that on a saturday night you have nothing more interesting to think about than this..you sound like a really nice tollerant guy.. maybe you should write down his audi reg number and contact the landlord to report this terrible crime, or contact crimestoppers..
edit…btw the crimestoppers number is free and after careful consideration i think using an 0800 number paid for with my tax money for anything other than the most serious of crimes would be an abuse of this service and i consider this to be theft of my tax contributions…
