Hard to say, I know lots of true hockey fans. They pay for tickets to see their favorite team, and they watch the whole game. They don't leave 4 minutes before the game is over. They don't miss the last goal of the game, and they don't miss the 3 stars.
The biggest faux pas by far has to be our Prime Minister Stephen Harper leaving Team Canada's game against Finland before the singing of the national anthem after the game! Now, I have seen previous examples of heads of government watching sporting events and not leaving. During the Rugby World Cup Nicholas Sarkozy watched all of France's games. He was even there in defeat against Argentina and England, and was seen singing the national anthem with everyone else. New Zealand's Prime Minister Helen Clarke stayed to the bitter end for the All Blacks defeat in Cardiff to France in the 2007 Rugby world cup quarter finals, not leaving early. Though kiwis contend they left the world cup early last year.
Harper claims to be a huge hockey fan and a Canadian nationalist. Leaving the hockey game early really doesn't help this cause. This just goes to show why Stephane Dion is more trustworthy than Harper. If he was a real leader and man of the people he would have stayed to the end, and sang the anthem with the crowd. He is also not a true hockey fan, because we stay to the end regardless of score.
