Perhaps it might be so in some village, but in Poznan -
- clean, new trams. Even the older Konstal ones are getting renovated.
- who speaks to tram/bus drivers? the stops and the buses contain all the information you need
- it's very reliable. Peak time service from my suburban place to the centre is trams every 3 minutes.
- Poznan MPK is very efficient.
- cheap as chips
Does anyone know how this work in szczecin poland?
Depends if they can be bothered to chase you up for it. Polish bureaucrats are very petty - they'll spend hours chasing someone. I'm more surprised that they allowed you to get away with it without a Karta Pobytu/Dowod Osobisty, but that's their fault. The sensible thing to do is to go and pay - much easier than risking them taking you to court, finding you guilty in your absence and then you getting found out in the future.
About my only problem with Polish public transportation is the morons they employ to check tickets. But this is the same in almost any country - revenue enforcement officers tend to be morons by nature as the job doesn't involve compassion or understanding.
