The Budapest Metro has a rather odd ticketing system. Tickets can be bought from a machine or from a ticket-seller, but then they are checked by people called 'Kontrollers', who stand near the entrances to the trains and ask to show your ticket. Of course if you've got two or three people checking tickets and hundreds or thousands of people using the Metro at rush hour, most of the people simply breeze through whether they have a ticket or not.
It goes without saying that being a Kontroll is a pointless and alienating profession. I've heard stories about Kontrollers simply being ignored or told to fuck off, and while of course there's a fine for being on the subway or the tram without a ticket, technically the Kontrollers can't enforce it - they have to call the police, who don't like being bothered.
A few years ago there was a movie, also called 'Kontroll', about a group of Kontrollers who live in the subway without ever going to the surface. They deal with the scorn of the public and the indifference of the suits downtown. To pass the time they dirnk during their shifts and go 'railing' - that is, having races along the tracks to see who can out-run the next train. It's mostly a fantasy but it captures the spirit of the profession fairly well.
