Prague underground

I had only one encounter of the police checking for tickets and the ticket validity in the underground.

The first time I met one, I was going down the escalator. He was not in uniform and was attending to two young girls but turned to me immediately when I walked pass. He held out a badge in his palm, while babbling to me in some alien tongue. I thought he was a fat tout in the underground trying to sell me an ugly brooch.

So I hurried even more quickly away from him. He chased after me shouting something until I registered that he wanted my ticket. I felt rather sheepish. He scrutinised my ticket carefully, then snorted his acceptance and returned my ticket to me.
