How to get free parking in carparks without wasting too much time

Ever come across car parks which only let you park for 2 hrs before they start charging you by the hour?

Buy a bright orange witches hat to put into your car boot. When your 2 hrs is up, just drive your car out of your parking spot and place the witches hat in front of the spot. Drive out of the car park and drive back in again and go back to the same spot. You would have only left your spot for 5 minutes so it won't look suspicious. Remember to set your alarm on your mobile to warn you to go back to your car and drive your car out and back into the car park!
