This year, I’m wishing Merry Christmas to my customers at Summit Coffee by walking my talk and giving the gift of sustainability. In the spirit of Gandhi, and Summit Coffee, I’m being the change I wish to see in this world by forcing reusable plastic travel mugs on all our regulars.I love the coffee shop I work at, and I’m proud to caffeinate Redwood City’s finest coffee fiends, but I would be prouder without the hundreds of paper cups and plastic lids we fill our trashcans with. I’m just as responsible for contributing hundreds of paper cups as our customers are. If I want the world to be more sustainable about consuming coffee, I can’t wait for everyone else to decide to switch to travel mugs. I, the barista, have to be the change. If I don’t want to see to-go cups go to waste, it’s my job to refuse to waste them. It’s my responsibility to offer an alternative. So I’m converting customers to travel mugs, one cup of coffee at a time.This marks the first year of a hopefully lifelong tradition I plan to carry to my future coffee shop. Most coffee shops offer some kind of customer loyalty reward, but why not reward regular customers with a free reusable travel mug? They’re the ones who come in every day. Sure, it’s not cheap. It’s an investment. Just think of the money you’ll save on the long-run on hundreds of single-use to-go cups. Just think of the business your commitment to sustainability will bring you. Just think of the waste your coffee shop won’t be contributing. One person behind the counter in one coffee shop touches the lives of hundreds of customers every day. It’s that easy to make a difference.
