In our country, a lady was walking a dog by the block of flats. The police wanted her ID. Of course she didn't have it. The policeman told her that even if she went around the corner to the dairy, she should have it with her. It happened to my husband, but away from home. He saw what he didn't even want to see. He was taken to find out, where he waited for 6 hours. He also paid a fine then, I just don't remember how much. Since then, he has carried his ID everywhere. She doesn't have a passport, the tram was not enough.
