Meter Parking

Today i decided to meter park because i was just going to be on campus to eat and then leave so the meter sounded like a good plan. So as i put money in and seen how much time you get for the value of the coin you put in. For example a nickel is like 3 minutes a dime is 7 minutes and a quarter is 15 minutes now come on mow 15 minutes I'm calling bs on that one.And another problem i have is u can only put money in for one hour of parking any extra money u put in after an hour basically is a donation to the school this needs to be taken car of.
