I came to replace a screw in my car, and the guy helping us didn't really know what he was doing. We took out another screw from my car, to match it. But it took the worker almost 15-20 minutes to find a screw, which was too large. The worker went to his manager to ask questions about the sizing, but the manager didn't seem helpful as he was occupied with other things. We then tried several more screws that didn't fit. I ended up purchasing a pack of screws and washers, which was the closest size to the original screw. It costed me almost $10, which I believe is pretty pricey for just a screw.
