2079 cups of coffee

I've spent two weeks in CMS (pictured above) in Cambridge, and am currently in a 3 day meeting in Manchester. Here, we have real cups and teaspoons, but milk is only available in tiny plastic containers. In Cambridge there were jugs of milk, but disposable cups. A lot of disposable cups - perhaps a hundred people, and drinks twice a day for 10.5 days. That is 2100 cups. Minus 21 (I brought a mug) = 2079.

Even if you don't plan to go stealing sheets and chewing twigs, taking a mug to meetings and conferences would seem a particularly easy thing for everyone to do. Apparently even starbucks are in on the act and will give you a 25p discount.
