Nothing
The site lists a bunch of times for pick up after the location is closed and doesn't indicate this until after the reservation is made. When I called budget about the issue, they had the attitude that I was a problem, they didn't even apologize for the inconvenience. I had to take an Uber in pouring rain to get to budget just to find they were closed which resulted in me having to pay for my ride both ways unnecessarily. The agent I spoke to was pretty nonchalant about the whole ordeal which I found rude.
