Blake: That watch costs more than your car. I made $970,000 last year. How much you make? You see pal, that's who I am, and you're nothing. Nice guy? I don't give a shit. Good father? Fuck you! Go home and play with your kids. You wanna work here—close! You think this is abuse? You think this is abuse, you cocksucker? You can't take this, how can you take the abuse you get on a sit? You don't like it, leave.
In the above dialog, I don't understand what he means saying " if you wanna work here, close". What does close mean here?
