Movie I can't remember name of...I saw the DVD and I think it said it …

That sounds a lot like the movie Clerks (1994),which is about a guy, Dante (Brian O'Halloran), who works at a convenience store.
It's a Kevin Smith movie; it's the first movie Jay and ดูซีรีส์สั้นจีน Silent Bob are in. A sequel was released in 2006. It wasn't bad, but it wasn't as good as the first one.
