Not OP either. Here there aren't turnstiles to access the commuting train, but there are controllers on board from time to time. With seldom use, it's just better not to buy a ticket (read: to bluff). Numbers made up and simplified but in the same ballpark: Round-trip ticket across town: 10€ Monthly pass: 50€ Fine: 70€ The chance to be controlled is roughly 1 in 10 for a round-trip. So if one did 5 round-trips in a month, on average one would pay 70 x 5 x 0.1 = 35€. Which is a good price with acceptable variance fur such usage. When caught just pay without fuss. At some point (between 7 and 8 round-trips) it's more cost effective to just buy the monthly pass, as the average cost of not buying approaches/goes over such threshold.
