I found this on the Gm-Volt site and pasted it for enjoyment. The next paragraph is also pasted and not written by me.
"I always welcome our friends and visitors to freely plug-in to our EVSE at home during off-peak hours, which is mostly during the weekends and holidays when they come for a visit. But some people that charges without asking permission are giving a bad rap to Tesla. Don't be like this Tesla owner! Fortunately for him, the homeowner is like a saint who wouldn't bother to file charges of trespassing and theft of electricity."
