I have worked at both Google and Facebook and this was an annoyance for everyone. People would come into the job and be promised the normal salary+benefits and then be told about the unlimited Odwalla and Aldale being open all day and how the food is amazing and then suddenly the most profitable companies in the world "realize" that these things are expensive, cut back, and expect something other than to have their world class employees go somewhere where they are treated a bit better. I will never understand not continuously investing in your employees, especially at the best companies on earth.
