I have no problem in asking a diner to leave for two reasons: 1. If they are rude to my staff. No one has that right. If we make a mistake, allow us to rectify it. 2. If they are loud and abusive at the table. They have no regard or respect for the other diners, who may have worked very hard to save up their cash to afford your prices.

Success is born out of arrogance, but greatness comes from humility.

It's not about what you achieve, it's actually what you do for your industry and that's what I think is important. And when people look at me and they see my achievements with the restaurants do you know what I think? I think I did more than that. What I achieved was teaching young men and young women when they were young and inspiring them.

How many chefs when I was a young boy shouted at me during service? All I ever said was "Yes, chef." The customer is the most important. If the chef overreacts, fine. At the end of service, you apologize.

I can't imagine anything worse than trying to impress a girl with dinner. To be honest, I'm always impressing myself, not other people.

Do I shout, belittle or swear? No. I have sufficient confidence within myself to control my environment just by my presence, just by working hard and leading from the front.

When you walk down the street of Kabul your values for life changes, they do change.
