I guess the problem is that we define "living at" Google to mean sleeping there. In many ways eating there is more relevant. Someone who sleeps in a car in the Google parking lot but eats elsewhere at least gets that modicum of outside interaction. Someone who eats at Google before going to a real home and flopping straight into bed does not.

Of course, companies like Google know this. The whole reason they provide the meals is so that people's attention stays focused within Google instead of elsewhere. That probably leads into a whole 'nother discussion of whether meals at work are really a good thing, but I'll just leave it there for now.
