Where I worked this summer, we all had our own mugs. I usually came in with a cafe au lait or a mocha in the morning in my travel cup and then used my mug in the day at work. I love my travel mug because it has a "clip" function that clips onto a basket or your handlebars!

Currently, I started the coffee trend in the office with the grad students, being the first one to bring a pot in! We all have mugs and are pretty dang eco conscious!
