Friend of mine works for Linklaters, the big law firm near the Barbican. They had Hamilton in to give a motivational speech. During his visit the reception had to be cleared, he insisted he didn't want to meet or talk to anybody (outside of his 'performance') and top quality champagne was a must.
My friend is an avid F1 fan and was looking forward to meeting a top driver, but he said Hamilton was an absolute prick. Seems like the Ego has landed.
