There is a scene in the movie Drinking Buddies where Gene and Luke are talking in a bar.
Gene: I've been ten minutes out since I got here. I had one of these, and then I said, "I'm gonna have one of those," and then here I am.
Luke: Yeah, it's hard once it starts going in.
What does I've been ten minutes out since I got here mean? Does it mean Gene has been there for ten minutes? The scene appears to be after they have been at the bar for a while, longer than 10 minutes. So I don't quite understand what Gene means here.
