When returning the car in the morning, no staff was present at the rental office. We waited for 10 minutes for someone to return from the airport and they prioritized helping a new customer first. The entire process from arriving at the office to finishing the return took half an hour. As a result, we barely made it to our flight after handling tax refunds, baggage check, and security. The rental office was informed of our return time in advance, so they should ensure enough staff during busy hours.
