Don't care too much for money.

I've been at my job for almost a year, and so far there's only been two days I haven't brought my own lunch with me. Sometimes there's been catering, but that's still not food I went out and bought myself. Both times I brought it back to the office to eat, too. And it's not as though I take a long time to eat.

I feel in light of that, taking a leisurely afternoon break and leaving the office for about a half-hour to sip coffee and read is completely justified. I'll have to do it again on Monday.
