I was already paying for all those things, and they were sitting idle during the day while I was at the office using another set of them that my employer was paying for. Except the snacks, I miss the free snacks, but my waistline doesn't.

I'm curious what the IRS will have to say about it. If self-employed people can deduct a certain amount of their square footage as an "office expense", can I do that too? All those things you just listed are now part of my employment.
