Jacko,
People behave differently to each other, people think differently to each other, just because you find it hard to imagine how anyone could act in such a way does not mean that they would not act in that way. Some people are materialistic and can't believe that if everyone had the money they wouldn't be spending it on D&G gold plated phones, flash cars and other status symbols. Personally I can't understand the materialistic mindset, but it doesn't mean it doesn't exist. Viva la difference. People are different (and no points to the first person to reply "I'm not"), can't we just leave it at that?
As regards Sammy Mc, I have no strong opinion either way, but in general would prefer an up-and-coming manager.
