It's okay.

I was in a hurry when picking up the car and didn't notice the fuel gauge wasn't full, it was about one bar short. Realized it after driving a few kilometers, so I didn't bother to go back.

Small office, not many people, short waiting time, service attitude was acceptable

The rental staff explained the issues very clearly.

The total amount of purchase have been withdrawn from my credit card and after dropping the car off, an additional 60USD was withdrawn with no explanation from budget, I tried to reach the customer service and they promised to resolve the issue but nothing from their side yet !
