They were expressing their appreciation for the driver, who often arrives first, to voluntarily use their “plug” or Level 1 charging cord and leave the more convenient Level 2 connector available for the person who arrives later. Nice gestures from both of these drivers I think.
Thank you for reading Plug In Sites. I appreciate being able to share charging spots, news, ideas and photos with you over the past few months since starting this project. Stay charged, drive electric and have a happy and safe holiday!
