I know almost every line from that movie, and never noticed the 3rd door. Damn I ain't too quick. I have to imagine the video store is closed. I just moved, but 2 or 3 in my old town closed in the past few years. With on demand, Netflix, and those Redbox kiosks, video stores are kinda obsolete.
It was a pretty crappy video store to begin with. I worked at a mom and pop place like that (but quite a bit nicer, bigger, and pretty much the only game in town) back in highschool for a short time and it went under years ago. Would make sense if they have maintained it to some extent as a Clerks/Askewniverse roadside attraction though.
Well, yeah, with Randal working their goading you into lashing out at him so he can revoke your membership it couldn't be a great place to get movies.
