That's not really fair, America is just like any other part of the world -- some places have good ingredients, some not so much. I had great food in India, but I also had some that gave me a major case of the runs. I've had plenty of really great food in America, but I'll grant that if Pizza Hut is your thing, then you're after something different from me.
Also, the woman in question was coming from the UK, as I recall, so alleged food quality in America wouldn't be terribly important to her.
I think the parent comment is trying to allude to Pizza Hut in india being higher quality than Pizza Hut in America. It's an apples-to-apples comparison.
I know that the McDonalds in Germany at least used to be considerably better than the McDonalds in the USA. Pizza Hut being better in India sounds totally plausible to me.
