I rented a pickup to help some people move out of state. Long round trip, 2000 miles. Just as I was about to pull out of the renters parking lot, I noticed the truck has gone 11,000 miles on the last change, according to the decal on the windshield. I stopped, pulled back in, and asked if they simply forgot to replace the decal, assuming at least one change had happened, but wasn't indicated. They kinda smiled, and said no,it wasn't changed, but don't worry about it. When you get back, that truck is planned to be sold.
