Definition: Given a real-life anecdote of a complex ethical situation, generate a suitable title that describes the main event/root cause of the situation. Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: Couldn’t figure out a good way to write the title, but let me explain. I was at a restaurant with two bathrooms: one for men and one for women. They were both the type of bathroom that only has one toilet and is meant for one person at a time. Anyway, both bathrooms were occupied and one girl was waiting to go (I’m a guy). As I walked up to the bathrooms, the person in the men’s bathroom walked out, so I immediately walked in even and used it, even though the girl was waiting. After locking the door, I think she started yelling at me for cutting her? It was really loud in the restaurant, so I couldn’t tell for sure.

AITA? 

On one hand, it was technically the men’s bathroom... and since she is a girl and I’m a guy, and no other guys were waiting, it was my right to use it. But on the other hand, since it was a single-occupant bathroom, there was no reason that she couldn’t use it, even though it was marked for guys.
