I had a bit of a chat with one of the women who run the DiNA (one of the on-site cafes on campus). They go through about 15 boxes of teabags in a day. That's just them. Figure the same with Pebbles (the other cafe) and that means that there are roughly 3000 cups of tea sold every single day on campus. Now if you consider that there are maybe 1000 people on campus, that means an average of 3 cups of tea sold for everybody in a day.
This makes me smile for some reason.
