I am having problems at work charging my car when the only four spots for charging in our parking garage are always occupied by other Tesla owners. Unfortunately, they are all plugged in, but by the early afternoon, three out of the four cars are already full. I have tried for the past two days to come back to the garage two or three times, To try to find an empty spot, to no avail. What kind of note should I leave for the other Tesla owners to let them know that there are other cars that need to use those spots. I have used an app that identifies all charging spots in parking garage is in Miami, and I have left messages, however it seems that this owners are not tracking or using The app. I appreciate any suggestions of the best wording to use so as not to offend my fellow Tesla owners.
