Side-View Mirrors: MIA!

Sorry but not understanding what a “side view mirror” is versus a “side mirror” or from what the manufacturer calls a “rear view mirror”, might explain why a person is still behind a parts counter after 35 years. Seemed perfectly clear to me what happened and what she was looking for. Whether its plumbing, carpentry, car parts, etc., not everyone can know all of the precise terminology for all the professions so it is part of the sales person’s job to assist in identifying what is needed without upsetting the customer and even, gasp, offer helpful advice. Lecture over.
