Germans pay for it. Either by tip, expect to pay one euro. I didn’t have change, two euro. Sweden has clean, free lavatories with auto sensor to switch on light hot water and paper, hot air dryers. I blocked a German toilet, the old lady in her white overalls dozing as I went in had gone for a break. Good! Run! Blocked toilet no tip, run!
In the woods? Find a branch or tree trunk, place a sock or flannel to protect your testicles if you’re a bloke and go! Definitely no one around. I never did that before. Yes, cover it all up with moss twigs earth rubble. I had tissues and Wet Ones baby wipes as well. No tip that time.
