Okay, pay me the money you were going to spend on snacks and the money you were going to pay the person who you pay to fetch the snacks, and I'll go fetch my own snacks or order them off the internet to my desk. It's arguable whether it's actually a perk for me to spend 8 hours in a row at my desk, but even if we accept that claim at face value, it's still not a significant factor in any decisions I make.

Perks are things you give me that I can't get for myself, like health insurance which you use collective bargaining to get a lower price on. Snacks aren't that.

And while it's anecdotal, I've seen people take multiple-thousands-of-dollars pay cuts to work at places with "a better culture" where the only discern-able differences were soda in the fridge, beer on tap, and a ping-pong table or similar: all things that if you put a number value on what it's worth to you, aren't worth it. Culture does matter, but it starts with valuing your workers enough to pay them and not use irrelevant "perks" as an excuse to pay them less.
