The problem I have with parking authorities is fraud. When the meter employee gives me a ticket for a different meter, or when the parking ticket fine is $200 instead of say $30, or when the restrictions are absurd/vague ("You can park here for 2 hours m-f except holidays except 9-11 except in green spots except you have to display the ticket in your window except you need to be 6 inches but not 12 inches from the curb except except except except")...
... then this is the part where I start to suspect I'm not paying for the parking I'm using, but instead I am paying for someone else's large and undeserved profit.
