Why can't you store it at your desk? My biggest pet peeve in the office was the people storing personal items in the kitchen. I don't need to see your machine with (don't use) stickies on it or the random assortment of blender bases. I also don't need to see your dirty tupperware in the sink.
To be clear, it was not just for my personal use. I brought it in at the request of my team and it was available for anyone to use. The team had a collection jar and we all pitched in for maintenance and supplies, just like we did with our team’s foosball table (also later removed by management for poorly specified reasons).
