I also know that Google in the early days had a policy of free food for its employees and I sampled some of your free food at lunch today it was very good um you obviously uh have to spend a lot of money you’ve got 182,000 employees so giving them lunch or breakfast or dinner every day or for many of them every day you must have a calculation that says are we spending this much on food we’re getting this much higher productivity and how do you uh assess that and why do you think other companies don’t give away food as much as you do quite cont I think in technology if you go to the Bay Area I think a set of things which Google has done as part of now standard modern workplaces uh in the Bay Area but uh you know people value inperson uh collaboration to us you know I I can recall several times you know when I was uh working at Google early on being in cafes meeting someone else talking getting excited about something and so it Sparks creativity it creates a community uh and and and I think the benefit that comes out of it you know far uh dwarfs the cost associated with it
