Charging at a strangers house

We spent the last week in an alpine Chalet and had to leave the car in a public parking halfway down the mountain. Upon arrival, the battery was down to 20% SOC. I read that leaving it below 20% or above 80% for extended periods of time was not too healthy. So I asked at a house next to the parking, if I could plug in the car for a while. They seemed friendly and agreed immediately. I told the man that I would need about 40kWh, and asked how much the electricity costs. He said he had no clue and I would have to know.
When I came to pick up the car, I gave him about twice as much as the electricity would cost at the most expensive rate known to me, and about three times as much as I pay at home. That was when he started complaining. He said when he goes to the gas pump with his ICE car, he wouldn’t get a lot of gas for this price. And if he knew that I was going to pay so little, he wouldn’t let me charge. Same for me, if I knew he would be discontent, I would rather drive 20 minutes to the next Supercharger, get free electricity, and still be welcome.
I never paid so much for a charge as I gave him. Usually if the electricity is too expensive at a public charging station, I just drive on to find something reasonable. But I paid him more than I usually would, because I wanted it to be a good experience for him.
I read about mostly good experiences when asking strangers for a plug. But after this incident, I will think twice next time.
What were your experiences with charging at a stranger’s house?

Spending Bitcoin while charging the car

When I go some place new, I always check out what Bitcoin accepting venues there are. I usually try to prioritize shops that accept crypto currency.
When I drive some place far away, I have to charge the car on the way. No big deal, usually I can eat, drink or go to the toilet. All those activities, I prefer not to perform in the car while driving anyway. When I’m done, the battery is charged enough to continue the journey.
But how cool would it be to combine the two. If there was a restaurant that accepts BTC next to a supercharger, I would eat there for sure. Unfortunately finding this information manually is a hassle. That is how the idea was born to write a simple script to correlate charging stations and Bitcoin shops. I did it only quick and dirty. It could be improved a lot, but I’m not sure that is necessary.
