As you can see, mochas (the bulk of my "café" purchases) are the bane of my wallet. On the one hand, I do enjoy them. I don't think that all spending is bad if you feel you get proportional pleasure out of it and there aren't cheaper options that are equally good.
So I enjoy my mochas while sitting in bookstore cafés... But I'm not sure I'm actually getting $80(!!) worth of pleasure out of them each month. That's like a mocha a day. What was I doing in August?? Two mochas a week seems more than sufficient for me, and that would only be $26 a month ($3.25 × 2 × 4). Huh. So I suppose I buy café foods along with my mocha far more often than I thought I did...
Like I said, I'm not against buying mochas and food per se, since I do enjoy the experience of consuming them while sitting in bookstore cafés. But I am against mindless, unconscious spending. I really wasn't very aware that the café purchases were adding up so fast, and sometimes I do just buy the mocha at the bookstore out of habit.
So. Hopefully I can keep track of "Have I had 2 mochas this week yet?" in my head from now on. :P
