The parking lot near my place of employment is approximately one-third two-hour parking; it is, of course, the more convenient parking - consequently it is far easier to park there than nearly anywhere else. It, too, has the ability to save on time to park as well as a reduced walk from the car to the building.
Sadly, the two-hour parking is actively manned by a team of clipboard-armed men in little cars which will frequently note those cars which are over their time limit and provide the following services:
1. Clamp a convenient boot on the driver's side front tire
2. Place a helpful note on the driver's side window
3. Find a bright-orange cone and place behind the vehicle
4. Give you the opportunity to donate anywhere between $25 to $40 to pay for the gas in their golf cart.
A far more effective use of resources will be to simply park in the all-day parking.
