There is nothing more frustrating than having enough knowledge to look up your own part to avoid mistakes on someone else's behalf there, using the part vendor's own system due to working in automotive...then calling the vendor's store, in this case O'Reilly Auto on Rainbow and Windmill, and being told that they have the part # you want, and they will hold it on will-call for you....and.....you arrive at the store to purchase said part and the store manager tells you it is a non-stock part, they've never had it, and when the person who spoke with you on the phone pipes up that he took the call the store manager lied and said he was talking about something else....even though the other parts counter person then tried to help me and did indeed take my call, and told me the part that now doesn't exist was in the store over the phone. I guess I should be used to this type of thing, since I manage an auto shop, but I was very impressed with this store's ability to disappoint.
