Great news! I can't even get them to put spring water in at work. Have to bring my own.
For one cup brewing you may want to consider
this as well. I've been using a SwissGold one-cup for years. I use it often now, not for cupping but for informal sampling of roast levels, rest times, etc. They brew a great cup, are easy to clean and are unbreakable. I also use it for traveling.
