"You (as the employee) are just donating more time & money to the employer."

Not sure if I agree with this. You aren't necessarily required to eat and work at the same time just because you are getting free food. Secondly, an extra ~$10-15 bucks a day per person is a relatively minuscule amount of money for a company (keep in mind that if this was distributed as salary to employees, it would only be about $5-10 a day after taxes). So, essentially the employee is enjoying a meal that is being paid for with pre-tax money.
