Playtime and toys are good for kids, or they wouldn't buy them. McDonald's can provide that experience. And having dinner with the family is good for kids.

When you raise prices, you've got to make sure you get it to the bottom line. You can fritter it away because of the way you're running the business, with maybe not a totally disciplined approach.

But we had a pretty diversified portfolio of businesses around the world and things tended to offset each other. But one or two years ago, we had a lot of things happening at the same time.

McDonald's is almost 50 years old. For 47 years we had a pretty consistent track record of being able to deliver admirable sales.

And so if your competitors aren't growing, if there isn't a competitive reason to grow, and you want focus and discipline to add customers to existing stores, you adjust your strategy.

I think we have a great track record on being relevant, on identifying consumer trends, needs and wants.

But, on balance, we seized the marketplace. We've got a great infrastructure. And yes it's struggling in some areas because of some external factors and some internal factors.
