"Having worked in customer service for one of the area's largest auto dealerships for the past six years, handling difficult customers was a situation I had to learn to handle pretty quickly. A few weeks ago, I recognized a customer that had recently purchased a new vehicle. He stormed through the door, placed his keys on the counter in front of me, and said that he demanded a refund on his new purchase because the check engine light had already come on inside of the car. Knowing his new vehicle was under a full warranty, I let him know I'd have a member of our sales staff come out and take a quick look. I also let him know that our service department was not working that afternoon and, if needed, we could schedule him for a diagnostic test at his earliest convenience. We ended up giving him a loaner vehicle so his new car could be taken care of on Monday morning. I could understand his frustration, but he left in a better mood than when he arrived."
