Thanks for answering! There is enforcement in Europe, more or less depending on where you are. In the UK it's not unknown or even not uncommon for homeless folks to board busses or trains and maybe taking a nap (or a good night's sleep) instead of sitting outside and freezing. In the UK and in Greece beggars are also a common occurrence. >> The risk of being murdered is low, but the risk of an unnecessarily unpleasant experience is high: begging, harassment, groping, smoke-filled train cars, food scraps, having someone spit in your face, urine, vomit, and feces are stories every commuter has. Inter-city trains are generally fine. That certainly sounds extremely unpleasant. What I'm trying to understand is how high is the risk, really, and whether it is higher in some cities than others. I mean because I still can't imagine public transport where people will spit in your face in the bus or in the train. Although I've seen people getting sick (and then jumping off at the next stop, bastards) on London busses. In London, being puked on of a night out is a real risk but then it's nothing to do with public transport. Anyway, how high is the risk of such unpleasant experiences in the U? Why is it that way?
