I lucked out with recent rental. They tried to charge me for a windshield chip.
I had taken pictures at pick up and hadn’t even noticed. A couple hours later I noticed the chip from inside the car and took a pic. Very fortunate for me, one of my original pictures captured the chip as well.
So I had one low detail image from pickup, and one detailed pic from 2 hours later. They accepted and removed the $500 charge.
