My FiL is a truly horrible man!
He's mean, racist, doesn't care a damn about anyone but himself, treats my DH like filth (he doesn't treat me like muck as I avoid him like the plague) and yet expects everyone to dance attention on him.
When my MiL died, he started 'chatting up' a woman at the funeral! The woman in question (I shan't call her a lady) had been a casual aquaintance of MiL and it was common knowledge that she was 'after him' or rather 'after his money'! Two weeks after MiL's funeral, he went on holiday with this woman!
He made an absolute fool of himself over this gold digger, and when he forgot our DS's birthday (his only grandchild) because he was too busy planning yet another foreign holiday with her, DH told him that his behaviour left a little to be desired. His reaction to that was to threaten to cut DH out of his will! DH was really upset, so I went to see FiL, told him exactly what I thought of him,and where he could shove his money and have never willingly spoken to him since. If I have to see him, very, very rarely and always by accident, I'm civil, say hello, but no more than that!
He's been poisonous for the 37 years that I've known him, and apparently wasn't even a nice child!
Just because he has 'a few bob' he expects the world to revolve around him, looks down on everyone and is unpleasant to the core!
