On busy train to work this morning, train stops, everyone gets up and moves into the aisle. Man next to me remains seated and starts fussing with his bag and accidentally drops his laptop straight onto my foot! I say ouch and all he does reach down and pick up the laptop and glare at me as if it were my foots fault he dropped his laptop on it. I said something along the lines of its polite to apologise and he continues to just glare at me. I definitely didn't knock his arm or anything to make him drop it. Huge bruise on my foot now, really painful. Surely it's common decency to apologise, accident or not. Right?
