So today i was presented with a problem which i have encountered a couple of times before, but am yet to find a solution to. Im at the office and someone brings me a coffee from Costa. All well and good and much appreciated. The problem is the coffee delivery coincides with a much needed bowel movement. So without one of those weird USB coffee hotplate things, or microwaving it (that just seems wrong to me) how can i keep my coffee hot, while disappear for 10 mins to make myself comfortable?
