Where I park for my classes is all metered parking. I think there's like a 25 min max on the meters. Unless you have one of those cool handy dandy blue hanggy things, then you can park all day for free...and get dirty looks from people when you go back to you car at the end of six hours. <shrug>Here's a parking snafu:
My friends lived on a residential street, parking was allowed on the northbound side, but not on the southbound side. Signs were posted about this. One day, people come home from work/class and see that their cars all have tickets.
Turns out, the city changed the rules as to which side of the street to park on, changed the signs that day, ticketed every car. My friend S took his ticket to city hall to protest it. The clerk said "Well didn't you read the signs?" S: "I read those signs five years ago when I moved into the house. Why would I re-read them? Why would anyone think they had changed?"
Then S: "Why didn't you put notices on our cars so we'd know to park on the other side of the street?"
Clerk: that's a lot of work to do that!
S: How is that any more time consuming than ticketing every car on the street?
I took my sister to court a couple weeks ago. There's street parking IF you can find a spot. I said screw it and parked in the lot. I didn't know it was a city lot so I was stressing because by the time we got done it was going to cost me like $10.00. Soooo I was all prepared to pay when the attendant told me it was free with the handy dandy blue hanggy thing. Score.
