In experimental way I found out that in Austria public toilets free for people with disabilities. Twice had the same situation with them: the cashier sits at the entrance, and when I came in no one stopped me, not a single. Of course, with European charm.
In the afternoon the rain started and we went to sit nearby pizzeria. I drank tea and went to the bathroom. Faced the stairs. Friendly staff explained everything: you have to go outside, go through the kitchen, and there is an elevator. Again, I was allowed without any problems to use the service elevator, as in Barcelona. The toilet is not disabled, the door did not close when I went in, but it was ok for me. From the outside, the waitress was patiently waiting for me. Again, I was not rushed, staff smiled and behaved as everything is normal. And this is normal. Is not it?
During my travel in Europe, I got used to the fact that I can just go to the toilet when there is such a need. What I do not have to worry too much about these issues.
In general, I thought that in terms of my views on comfortable space and solutions, this trip will not change anything.
And it turned my world upside-down.
