The interesting thing about the slip up is that someone at the do was desperate to get the news out to the media. Were the Mirror there? If they were, fair enough but somehow I doubt it. So that means that they either picked the story up from the fans or someone else who was at the do.
That's worrying, not because of Garry's slip up, but because it shows that some people are determined to get negative stories out no matter what. Next time it could be something much more serious or damaging to MCFC, not to an individual's reputation for speech & language skills.
Years ago Billy McNeill made a similar slip when he was at a supporters' meeting. He said: "It's great to see so many Celtic fans" Obviously he meant City, but it's worth pointing out that the story of this cock-up actually appeared in City's programme as a bit of a 'whoops!' type of comment. It was supposed to be lighthearted but it did damage McNeill's reputation with some fans who thought his cock-up was a bit more deliberate than a simple slip. It was a simple slip, but it haunted him from time to time.
Often it's not the slip ups that are the problem, it's the way some people report them.
