Booking car was easy, but collection and drop off with Advantage not so much!

Pick up was longer than expected with a pushy up sell, it felt like the counter staff were getting annoyed when i wasn't purchasing extras i didn't need or want. They even tried to sell me insurance that was already included as they weren't checking the booking properly. Rental car drop off signage was confusing, as the signs were blue and in plain sight when driving in to the airport, but they change to yellow small signs as you get near the terminal, so we missed the entrance and were taken back on to the highway. This added another 15 mins to dropping the car off so we were almost late. Drop off staff were trying to move the car to begin cleaning etc while our belongings were still in it, luckily we were very organized or it would have been easy to leave something behind.
