Being a tea drinker in a coffee dominated Keurig world requires an extra step. You want clear water? You first must run that puppy on 4oz to clear out the previous coffee user.  Others have told me this is a myth, but I'm not buying it.

There are a few unspoken rules to a community Keurig. Whether it be coffee/tea/cocoa, is it too much to remove your cup before the next person? Also, keeping the water at respectable level seems like the right thing to do.

If you had to choose one, which is the bigger fail?
