I don't want to go to into detail about it, but my husband has a wealthy (VERY wealthy) friend who he knows through a shared hobby. I've met him twice and the first time if my husband hadn't told me after who he was, I wouldn't have had a clue because he was wearing scruffy (but clean) jeans and a shirt. My husband was competing and I happened to be standing next to that guy and we started chatting. He'd obviously seen me with my husband earlier because he asked "Are you X's wife? I'm 'John'" and we just chatted away.
My husband told me afterwards who he was, just as another friend of my husband's (we'll call him Y) ran up to me all "Do you not realise who that was?! What was he saying to you? What were you talking about?" Y is a massive
a-licker of anyone he thinks is well off or well connected. Quite full of
tit. He's not my favourite person.
A few months later there was another event and I happened to be there (I don't go that often, only if the weather is nice to be honest

) My husband had wandered off and I was just watching everything that was going on when suddenly I spotted X being cornered by Y. He caught my eye and winked, I heard him say to Y that he'd see him later and he came over to me saying he hoped I didn't mind, but he had to get away from Y. My husband came back and the three of us were chatting and he said within 30 seconds of meeting someone like Y he knows if they're just talking to him because of who he is. He said he knew when I met him the first time that I didn't know who he was and I said I didn't have a clue and he replied with "But when you found out who I was, your personality didn't change and you didn't change the way you were being with me".
He said he knew I was genuine when I was going to get a coffee and asked him if he wanted one, despite the fact that he is literally a multimillionaire.
He's in business with his brother (who is much better known and much more recognised) and apparently his brother is a very nice down to earth guy as well. My husband's met him, I haven't. They weren't born into wealth, their family wasn't very well off when they were growing up, all of their money is from hard work, but because they weren't born into wealth they've always been down to earth and it's never gone to their head.
Apologies for going a bit Mumsnetty there with X & Y and the mysterious hobby. I promise it's not cycling
Oh and he bought the coffee, and a tasty slice of carrot cake too.
