PamG, my hubby learned early on in our marriage that if he wants something from the autoparts store when I'm out shopping, he must send a note with me to the parts guy explaining what he wants. so I take my note into Napa auto parts and hand it to the clerk and tell him, "I don't know what this is, don't bother talking to me about it, but if you have the part that's great." Saves my one nerve.
