Why doesn’t Microsoft provide free food for staff as Google and Facebook do?
Microsoft culturally sees food through the lens of Star Wars: a capitalist empire with many free-market options that you vote for with your wallet. They pay you enough to think with your money.
Google culturally sees food through the lens of Star Trek: a socialist empire in search of truth, where the basics of life are made free for you to focus on the complicated. This also helps them in the competitive job market of Silicon Valley.
