Courtyard by Marriott Scottsdale Old Town

After we checked in and returned to our car to get our stuff we saw a sign in the parking lot that stated they charge for parking. I went back inside to ask because I was not aware of any parking charges. A different representative was at the counter and was not very friendly. When I asked, she stated yes there is a charge and when I said I was unaware of this through booking.com she immediately said, well I can cancel your reservation for you. I said no as it is not refundable, I then ask her why I was not told this when I checked in she said I should have been told and that person didnt do her job. She called her over and proceeded to scold her in front of me. This was very unprofessional and uncomfortable. I was not charged for parking but I thought I should pass this in.
