I parked at a Parking Spot last week. Amazingly, my clock in and out times are 2 minutes short of 24 hours. With my coupon, I was charged almost $7. The coupon deducted $11.70 from my bill. Previously, if I parked less than a day, it was always free - even with valet. This time, I chose the roof self parking (cheapest) and it still wasn't free. Seems that the terms of this coupon have changed. I didn't have time to pursue with the main office when I was there. Has anyone else had this experience or know what's up?
