That still meets the one coffee mug rule. When I drive to work, there must still be some coffee left in the thermos when I arrive in the parking lot. If not, then the place of work is GU (geographically undesirable). Oddly enough the GU designation can be used for rating potential dating partners, but I digress. In any case, getting a larger thermos does not affect the one coffee mug rule, as the holder on the console does not accommodate larger mug sizes.....I've heard that from other teachers who have stopped their commutes. Right now I commute about 30 minutes each way. It think a 15 minute commute would be ideal. Except for the winter. And that's the main reason I want to move to where I work. I hate driving on the highways in the winter.
