The line is long, deal with it. They have a lot of counter workers and the line moves quickly. Know what you want when you get to the counter so the line moves faster. Do NOT touch the parts when they bring them back to the counter. The people behind the counter are usually bilingual so if your English is not great this can be really helpful. The cashiers over the years have always seemed like they are aloof and tired but the service is fast and the parts are cheap so you get what you pay for I guess. I wish this place was better lit, it has restaurant ambiance lighting which is kind of annoying :/
