My grandparents are very VERY wealthy (in the millions), yet you would never ever know from meeting them. They've driven the same car from when I was tiny, their house is in desperate need of TLC, they don't buy anything they don't need, shop in charity shops, don't throw any food away etc etc.
To be fair, I'm the same. I earn a fortune but you'd never be able to tell and I like to keep it that way.
In my eyes, nothing worse than being flashy.

My clients finances would never enter my trail of thought to be honest. As long as they pay my fee, I'm a happy girl.
