Oil change. Car required conventional 0w-20 according to manual. I had a coupon for an oil change for $19.90. They don't carry that type of oil and I was up sold to a syn blend for $34.90. Ok. Then bill came to $50 with added services, eg. Fluid check With an objection the bill was reduced to $40. Interestingly the washer fluid was low. Guess they checked it. "Yep it is low."
