Just to add a little something to my item about Kerry Packer.
Seems he was in a casino at a no-limit table and was in his normal not accepting fools gladly role.
Another player was being a bit OTT and he and Kerry had words. Guy said, 'I am somebody you know - I'm worth $60 million'. KP replied ' Toss you for it'
Having money - Mastercard
Knowing how to use it - priceless.
