Not sure how far back this day and age goes. I was bitten on the finger (and probably lightly punched on the face) ca. 1979 stepping in between a man in his thirties, likely coked up, and a weedy law student he was about to hit. That was in downtown Washington. In the early 1980s I saw a guy get knocked down and kicked in the face outside a bar in the DC suburbs. In the 2007, I saw a guy get beat up by two other guys outside a bar in Vienna, somewhere between the Ring and the Prater. The first two were late at night, the latter was in broad daylight. (I had suggested to my wife that we stop at a cafe a bit farther from where there were drunks talking loudly. She ignored the suggestion and was greatly surprised at the fight.)
