This is 100% shot in western Canada somewhere. This is not like where you are apparently from, and not everyone skis on the trail. This was obviously an accident, he felt bad, shit happens. Its great he has vid/so many witnesses, that guy straight up assaulted him, and really acted like an eight year old, doing nothing more than to embarrass himself. He lost ALL credibility the moment he laid a hand on him.
If anything the British/Aussie guy should be filing a complaint against this older guy, you think an employer is willing to have their employees assaulted over an obvious accident?
