This is the second time that happened to me. Despite I parked there less than 1.5 hour (in 1 occasion only 31 minutes), the screen showed that I have to pay $10.15. I have to press the help button as the barrier would not lift. I can’t imagine how many people who just tapped their credit card without checking the actual time. The car park operator has a duty and responsibility to make sure their machine is accurate in charging.
