OK, I think in this case we can say it: freeloader! But talk about irrational behavior, this is costing the boss real money. A Tesla owner would not have to pay himself cash money to sit at a Supercharger, but he's certainly paying his employee more than the free electricity is worth, not to mention putting extra miles on the car and cycles on the battery pack. Any way you look at it, it makes no sense. And if I was the guy waiting behind his car at the Supercharger so I could get charged and back on the road to somewhere...well, I'm not an irascible guy, but even I have limits.
