We have glammed up our coffee cups and water bottles with cute decals to keep track of them at home/work/daycare/camp which becomes a conversation starter when people stop to read them.
We save time and money by skipping the drive thru and are eating healthier because of it. We encourage others to take similar steps when people ask about the fun decals. I have also purchased a couple of reusable cups with cute graphics for my friends so we can expand our circle of influence with their friends/family/co-workers.
