The irony that operational national security would be greatly improved if only they maintained a well staffed and resourced government kitchen for the Pentagon, but won't for many silly reasons. Oh no, lots of people would have to sit on idle standby many times, or gov't employees would get free meals.

I believe that orders probably do go up. I don't believe the sites/accounts using Google's 'how busy' have any relevance at all. As I understand it, these just use GPS/location data of phones.

It only takes one person to pick up 40 pizzas, after all. Perhaps they could look at time estimates for a new order as a better indicator, if such an API exists prior to ordering.
