- I was in the lot for one hour and 10 minutes. I got my ticket validated at Trader Joe's, which should pay for one hour. When I exited, they charged me $7. My daughter ran in with the ticket to make sure it was validated, and it was, and we tried again. Still $7. So I was charged $7 for the extra ten minutes? There was a parking attendant there and she seemed to think that was the right amount. For the extra ten minutes, I should have had to pay only $2.50 as that's the charge for 15 minute increments.
