=== Public transport ===

Blackriding is possible, albeit risky. Controllers are very frequent and wear civil clothes, so they cannot be noticed before the doors are closed. And since they do not receive hourly wage but salary depending on how many people they catch, playing the "dumb tourist" will have no effect on them; they want you in their record. The good news is that even if they ask you to pay the fine on the spot (40 euros), you can say you don't have the money and then you have two weeks to pay it. Or, give them a false address and just never pay it. If a controller catches you, use some idenification besides your passport, preferably one that doesn't have your real name on it. That way you're not in the system. First time you also may have a good chance to decrease your fine when you write a letter to the S-Bahn office. It´s wise to mention things like it was an unlucky coincident, you´ve been overwhelmed by the city and the mass of people and that you usually pay for the good and ecological public transport... :)

Trams and buses are easier to blackride: Trams have vending machines inside, so keep close to one and in case someone should ask for tickets just be at the point of getting one, after all, it takes a while to find some small cash, figure out which ticket to get, how to use the machine ... :) On buses you'll have to show your ticket to the driver when getting in, but they barely look at it so an old used one usually does just fine.
