Two things
1) Was that a real strip club and/or were those real strippers at the strip club where he confronts Dusty's boyfriend and his goons.
2) After that scene, in the parking lot while Mona and Don were discussing the conversation in the strip club, were those two clowns in the old car with the ridiculous huge rims (I hate that crap) a part of the scene, or some random thugs that just happen to drive by? They were all up in the camera shot and all.
