OK I know what the hell this is about.
Don't be fooled by the stupid "Charity" header.
Let me tell you about the charity events they hold.
They send out exclusive invitations to the rich people in name of charity. The dinner, it's going to cost $300 - $500 per head. Usual number of invitees/respondants is about 100 - 200 up class people..
Behind the scenes, a large part of the $$ is taken off for booking the place, the dinner/food, the organizing committee. (mind you, each of them gets more than what most people are paid each month).
the rest of the $$ goes to charity, of course. what's left of it.
Free photographer, indeed.
