Been 2 x, in 2020 and 2021. first time the door was open, I could empty the toilet and after 2 euros in I could tap water, electricity not used, 2nd time the door did not open and I could not do anything

Difficult to reach when the supermarket is busy. Lunchtime is the Super closed, then things are much better. You can buy electricity, but you cannot stand there for an hour or more, because then no one can supply it. How awkward
