Sometimes dangerous. I once moved when someone at the station smoked close to me, and he took it as offense and on the train he sat across the aisle from me and stared at me the whole ride until he luckily got off 2 or 3 stations earlier than me. I just kept pretending to read in my ebook reader while watching out of the corner of my eye and plotting my escape should he get off at the same station as me.
So you leave your place when someone smelly sits there?
