Okay, Im rolling now.
Little known Irish film called, The Courier

starring Gabriel Byrne, Ian Bannen, Andrew Connolly and Cait O'Riordan of the Pogues. (1987)
Andrew Connolly is Cait O' Riordan's sister in the movie. Connolly is a junkie. Both are sitting in a coffee shop. Connolly asks O'Riordan for money, she asks "why?" and he replies, with one of the most badly written and ill conceived lines, Ive ever heard.
(In a thick Dublin accent) "I don't ask ya wha your doin.... or who your screwin." (absolutely stupid)
From the same movie.
Gabriel Byrnes character was called Val and he was the head honcho drug dealer. At one point he passes a typical and cynical Dub. The "extra" utters the classic line....
"Uncle Val, the junkies pal." (one of the few good lines)
