After snapping this shot, I realize I could use a pit stop. I plug in the X at one of the chargers in their parking lot, walk over to the lobby, and ask a security guard if I can use their restroom. He lets me in. I do not even bother to ask if I can take pictures inside...he had already warned me against taking pics of other cars in their lot.
(Note that, earlier this month, I had contacted Tesla about touring their factory in Fremont, but there was no tour availability during the days I would be up here)
