Well today you get your answer. First of all, so that you’re not in suspense, I’ll get this out of the way: I didn’t win a car. Out of 56 coffees that I bought, I won 4 free coffees, and 3 free doughnuts. That’s a 12.5% win-rate. (I don’t bother calculating based on the values of the items, just the raw number of winning cups.)

If you’re interested in the whole spreadsheet—and, judging by past comments, you’re all just dying to see it—here it is.

Not that it makes much difference, but I kept track in OpenOffice.org Calc, instead of Excel, so if it looks a bit strange, that’s probably why.
Hmm. After all the fun I had tracking all of my coffees, this post seems a bit anticlimactic. Oh well. People don’t come to this blog for excitement—they come here for the pie charts.
