I got a fine for not getting my bus ticket stamped in Florence, Italy. Apparently if you paid it the same day it was one price and that price doubled after a week, month, etc.

Didn’t matter the machine failed when I stamped it because it was out of ink. I even tried to stamp it in front of the officer. He said I could appeal it in person in court. They know tourists aren’t going to appear in court to appeal. I felt scammed but after calming myself down and paying the fine the officer apologized and told me in a few words he hated his job.
