At this point, some of the responses here are making me worried that I may be opening a can of worms by trying to rectify this and that it might just be better to leave it be and remain on the DNR. I have yet to need to travel to a location that was only served by Hertz and my employer does not seem particular who I book with so long as it’s not outrageously expensive.
