Reminds me of the time I decided to plug my Leaf's EVSE into a 120V outlet while parked in the garage of a Korean shopping center in K-town (Los Angeles), near where I live.
I was strolling nearby when CarWings texted me that the Leaf had been unplugged. I quickly returned to my car and encountered a group of suspicious-looking Korean men surrounding it (I am Caucasian). One particularly large, beefy and stern one approached me and said in serviceable English: "I know you aren't a customer here. You can't park or use the electricity." He was clearly inferring that I wasn't a customer because I didn't look Korean.
I produced my receipt from the restaurant where I had just eaten lunch in the Asian food court downstairs and held it up for him. He didn't miss a beat, though, and continued to kick me out of the garage. Wish I'd had the presence of mind to suggest he was being racist (he was, in my opinion), but I was guilty of poaching volts, so I merely pointed out that some progressive retailers were providing charging stations for their customers, partly as an inducement to shop or dine there, and maybe it would be a good idea to let customers charge there. He would have none of it.
Signed,
Racially Profiled and Humiliated
