I have never ever seen anything like this.
It is not an ad but they deserve to highlight them.
A petrol station in Teneife, on the north of the island – El Mirador petrol station – has clothes all around on the filling stations to clean your hands, prevent from petrol, to wipe the windows, clean your hands, for whatever use.
It is easy like this. They decided not to waste paper towels for the everyday use, not to kill trees for that.
Thank you very much for being soooooooo careful!
