5000 Kilometers in the Western US

In February this year, exactly like February last year, and almost the same trip, the same strange incident happened. I picked up the car with a full tank and returned it with a full tank, but both times I got charged $65. I only found out about it after returning to my home country last year and multiple complaints led nowhere. This year I made sure to point it out when returning the car, and without asking any questions, they refunded me immediately! I can't help but suspect this might be intentional. I hope for an explanation. ALEMO is usually cheaper on the ZUZUCHE platform, but once you get there, they strongly recommend upgrading the vehicle and adding extra insurance. Various charges (like $145 for 8 days of GPS; last year, I got talked into adding over $700 of extra insurance and received a free GPS, the charges can be very arbitrary), and then casually being charged $65 for 8 days of rental at $15 per day, once confirmed, they would immediately refund it! Am I being overly suspicious?

The rental company was great, they provided an upgrade to a mid-to-large SUV, Hyundai SANTA Fe.

At the beginning of the rental process, they asked us to pay an additional insurance fee, but after negotiation, they agreed not to charge any extra fees. Everything else was very satisfactory and convenient, allowing us to choose our preferred or satisfactory model from similar vehicles.

The waiting line for car rental paperwork is understandable due to the high number of people, but once the paperwork is done, picking up the car is quite convenient. There are many cars to choose from, which is great.

Entered a lot of information, but the self-service pickup wasn't successful. Had to wait in line, which was very crowded.
