At least at WDW, very few of the public restrooms have in and out doors on them. Most of them you walk in, and turn and go around a wall.
I also think we have to consider that others sometimes have to deal with the consequences of our actions too. So our goal as humans shouldn't always be to do things that we can live with, but to do things that others can live with too. Thinking of others, and about how our actions may negatively impact them, is not a bad thing.
I totally agree that we should have due regard to other people's feelings. I just think that it's important to remember that however hard we try to please everyone, our actions may inadvertently have an unforeseen outcome of upsetting others, which I think can sometimes ruin your day unnecessarily.
While coming out of town square theater in June we found ourselves on a very busy sidewalk. We were trying to make our way up main street for a Be Our Guest ADR. Many people were sitting on the sidewalk awaiting the forthcoming 9pm MSEP. As there was no obvious way to get through, my friend attempted to move a stroller slightly, which was empty and placed next to a lady who was sitting on a large
ECV, with a picnic blanket, obviously saving a space for others to watch the parade which was still 45 minutes away.
My friend was polite and asked as she moved through the gap if she could go through to get out of the crowd. It was a split second decision, which given the extreme busyness on the sidewalk appeared to be sensible.
The lady was extremely upset and shouted at my friend that... "it was not a walkway" It was not our intention to upset the lady, at all, but it was difficult to foresee that by trying to get by it would cause offence to the person in question.
I could have understood if she had pushed the stroller, or if a child had been in it, but she carefully moved around it taking care not to stand on the picnic blanket or push into the people who were there.
Potentially this could have taken the shine off an otherwise perfect last day in the magic kingdom, and so I suppose my point is that unless you have deliberately set about to cause distress to others, or have done so by blatantly disregarding them altogether, you mustn't let events like this totally spoil your day. Sometimes despite our best efforts, we can end up upsetting people without intending to do so.
