There was no wait time, but they asked a bunch of questions that seemed pointless to me, like about my flight out of Salt Lake City and my destination. I've never encountered this with other rental companies. As long as I return the car according to the rental agreement, why do they need this information?

Very good, quick and convenient.

Rented a car in Salt Lake City, a female employee at the rental counter helped us finish the paperwork within a few minutes.

Salt Lake City Airport wasn't crowded; Alamo had relatively more people, unlike Hertz which had none. Overall, the efficiency was decent—waiting in line and picking up the car took about half an hour.

Pretty good. The service was enthusiastic, the car's condition was good. We rented a RAV but it was unavailable, so they upgraded us to a full-size Apache.
