We were at a hotel with an hpwc. There was a truck parked in the EV spot next to the hpwc with a cord attached to the truck. I was at my car which didn't need a charge so was parked down the aisle from the charging spots. My first brief thought was that there was an electric plugin truck of which I wasn't aware and I wondered how low the battery range was. So I went closer and noticed that this truck had ice'd the non Tesla charger spot, but pulled the Tesla cord across the hpwc spot, unplugged his gas cap, and stuffed the hpwc plug into his gas tank. I was just completely taken aback. I am refraining using the many choice namrs abd phrases that came to mind at that moment. Would have taken a foto but was running late on checking out. We let the hotel know as we were checking out, but this was a level beyond ice'ing and shows and immature and ignorant attitude towards EVs.
