I was the irritate customer yesterday when I was checking under the hood of my wife's car for a burning smell to only find that the oil cap was left off 3 days prior when we took it to Walmart for an oil change. I called the store and only got the shift manager and gave her a lashing of frustrated customer feedback.
I loved the lines she gave me, "We at Walmart want to make you 'the customer' happy and want to rectify the situation with you" then shift manager told me "Just to let you know our Tire & Lube technicians are not licensed mechanics but are certified by Walmart through company training..." That really made me have a comfortable warm and fuzzy feeling...<insert sarcastic laugh>
Really how could someone forget to but the oil cap on.
