- I am a foreign tourist, with a rental car, no internet on my phone and I parked my car on 9/20. I was instructed by a nice lady to insert my credit card at the entrance of the entrance and opt to stay for 3 hours. On leaving, understanding that I had prepaid, I didn't get any better instructions, I just went out with the car. I'm in doubt if I acted correctly. In my credit card it was charged $ 3,00. Is it ok?
