There was a time when I used to buy 4 tickets for any Ireland game I could and give 2 of them to some mates. I remember them asking for tickets for the "big" games like as though they'd die if they didn't get to the game. I automatically bought them tickets for the friendlies too. Sometimes they'd give me an excuse not to go and I'd accept that and sell the tickets for face value or less. It all came to a head when they said they couldn't be bothered going to the Georgia and Albania games in the last qualifying campaign. These are the type of people who should be the last ones to get any tickets. I certainly wont buy or offer tickets for them again. They're in the pub every weekend watching Manchester United so I'm sure they'll be quite at home there for the Ireland games too.
If we're trying to distinguish between people who are or are not "real fans" then I maintain that this type of people are not "real fans."
