Thinking of these things as "perks" is the first mistake. Is having a chair and a good computer a "perk"? For some jobs perhaps, but for people writing software they are a lot more important (though I'm sure someone will dispute that chairs are necessary). Likewise, good food and other environmental factors are very significant.
