The shop is something like an auto parts store. There’s a long counter, and most of the parts and surly sales assistants are kept behind it. Customers stand on the other side and wait their turns. You would almost expect to see a little machine dispensing numbered tickets, but no one calls your number here. If the shop is crowded, you need to be a little assertive. Stand at the bar and stare at whomever is most likely to be free to help you next.
