When returning the car near L.A. airport, there was a large outdoor parking lot shared by three rental companies. The staff giving instructions that night was very rushed, asking us to quickly leave the key and go. Later, Hertz charged us an extra day of rental, but luckily we had taken relevant photos, and Zuzuche actively helped me reclaim the rightful amount. However, I am not satisfied with Hertz's entire process. Everyone should be extra cautious about whether there are any extra charges on their credit card during car pickup and drop-off.
