The Union Square location was somewhat busy. We operated the machine, but after resolving everything, we still waited half an hour to get our car. Overall, it's acceptable.

Long waiting time

Short waiting time

The service attitude and queue time were acceptable, but after completing the paperwork, the car wasn't ready because they were washing it. I booked a Grand Cherokee, but got a Subaru instead, which is a much lower class, not good.

The car pickup point at Union Square, San Francisco, likely due to its proximity to the city center, has very enthusiastic staff, but the queues are extremely long. There are self-service pickup machines nearby, but due to operational issues, their efficiency is very low.
