On her Facebook page, Kerri Thoreson posts: "A souvenir from Saturday night ... $20 fine for missing our estimated return from across the lake by 30 minutes in the Third St. lot. Ticket issued at 10:19 p.m. which surprised me that at the mostly empty lot citations were issued that late in the day. Will have to read for comprehension the signs by the box where you have to predict how long you'll be parking. The 'mug shot' of the MAIN ST license plate is a hoot."
Question: Why do parking tickets make us angry?
