> Make the food in the café free. If an employee eats an average of $15 of food per day (the actual average at Google which is closer to $10) it would cost Microsoft $3,750 per year per employee to offer 3 meals a day. Instead of increasing starting salaries, switch to free food

I'm not sure this is a good idea. I wouldn't want my employer to assume that the extra $3750 (assuming the calculation is correct for now) will go in food. Salary increase sounds much better. But probably thats just me.
