USATODAY: Munich has best public transportation

I've had locals in some cities be genuinely shocked when I've asked how
to buy a ticket. Yes, as in /pay for/ travel. The Italian bus driver and
Bucharest receptionist could barely grasp the concept, and a woman in
Toronto clearly thought I was completely mad.

People in Italy and Romania might expect to ride without paying, but
Canadians tend to be very law-abiding. Some cities check tickets/
passes on a regular basis, e.g. Prague and Budapest. Some cities
border on anarchy, e.g. Paris, where people often just jump over/under
the turnstiles.
