Why can't I blunt the goddamned screws anywhere else? No indications, no hints, nothing. Just "somewhere you wouldn't mind vandalizing". Sure. Like the bathroom of the bar, where there's something that I have to peel off to see what's written on the wall? Nope. Maybe the fence on the alley where there's no one, or the trash bin? Nope. The XXX cinema, that the main character seems to hate anyways? Nope.
Obviously it's a specific section of a wall where there is no indication or reason to examine the goddamned wall.
Great.
