Greeks love breaking the law
Greeks enjoy breaking the law whenever they can. This is something that occurs frequently in Greece, love it or hate it. Most Greeks have breached the law at least once in their life. They might have parked unlawfully, constructed an unauthorized home addition, smoked inside a restaurant, ignored a stop sign or red light, crossed the street while there was a red light, failed to pay their taxes, or done something else.
For instance, parking on the sidewalks is common in Athens. In actuality, finding a sidewalk that you can walk on is more unusual! Thankfully, this doesn't apply to the old town. Curfews for bars essentially don't exist because of this, and it took Greece a while to take the anti-smoking law seriously.
Some people despise this quality, but others find it liberating. Numerous foreigners I've encountered have said that they relocated to Greece because life is "more laid back" there.
