Next time just tell them you left one in your last rental and it might be in lost and found (unethical life tip). I left a Canadian National Park Pass in a rental car once ($120/yr, covers admission to park). I went to the rental counter and asked if they had it. The attendant asked me what month it expired and he pulled out a box with probably 500 park passes and found one with the month. I suspect many people fly into my city (Calgary), rent a car to visit Banff and the annual pass is cheaper than the daily rate for vacation. When they fly home (to another country) they have no use for the pass anymore so they just leave it in the car.
