I work for a very large company whose name starts with a G, and they recently put on an event for employees to watch a movie. The person next to me was on their phone the whole time (they appeared about halfway through the movie) and even took a call during the movie while remaining in their seat. If it wasn't a corporate event I would have left. As such, I couldn't even say anything since it wasn't like I had paid for the movie and I didn't want bad blood. I was utterly baffled a working professional at this particular company could behave like this around their co-workers, thankfully no member of the general public has ever done something like that around me.
