Don’t Let That Bugger Get Away!
There are plenty of reasons why I don’t drink coffee (the taste being one of the larger reasons). Since I don’t drink the stuff, I don’t worry about anyone running off with my coffee mugs. However, in some offices this is a real issue. People will knowingly take your cup, fill it up, and take it back to their desk. Sure, you can confront them about their blatant disregard for your ownership, or you can get a better mug.
