The massages were not free. They were $80/hour plus tip. Or you could sometimes find 2-hour user studies to participate in that would give you a massage coupon, but it still required a $20 tip.
I have gourmet food at home and make as much as I did at Google. Plus none of that matters to me nearly as much as my health and not having to sit at a random office 5 days a week.
Gourmet chefs in the company restaurant, free massages and 25% pay raises for everyone? Fair deal (if working at the office is practically an option).
