Manly ferry commuters

Ferry commuters. Why is to so difficult to bring your own cup? Is it too heavy to carry? Are you worried your bag will get dirty? Are you forgetful? What can we do to assist you in bringing your own cup? Sonoma is the coffee place closest to where the ferry departs from. It really presents like you don't want to carry a cup - max 10 meters and then sitting down. What has our society become? You can do better! If we all switched to reusable coffee cups, we would divert 500 billion takeaway coffee cups from landfill every year.
