I found it interesting that their claimed value of 15-20k a year went unquestioned. At ~300 days a year, that's $60 a day. I'd value free food at a quarter of that at most.
I dunno; with inflation, it seems that I can easily spend $10 per meal. Maybe $15, and if I eat generous portions, $20. Seriously-- in San Francisco, it's not unreasonable to expect someone to spend $20 for a meal. Now consider all the extra convenience fees... $60/day (or $50/day) is not unreasonable. Of course, since it's a corporate perk, it should get a discount rate applied... but all the same, it's still valuable: more than $15/day (come on, dude: $5 a meal? Get real, or move away from North Dakota).
