Cinema etiquette

I read this article yesterday about cinema etiquette:

Interestingly enough, despite the amount of times I've been to the cinema, I haven't had any of these problems. Granted, I've seen people use their phones and eat a little too loudly before the presentation starts - such as during the adverts - but during the movie itself, the issues listed in the aforementioned article haven't been anything that I've had to worry about at the cinema.

That doesn't mean that I haven't come across any distractions, though. When Dad, my brother and I went to see the first Harry Potter film in 2001, there was a man who got up every twenty minutes to go to the bathroom; while I can't fault someone for needing the restroom, this guy had drunk a lot of sodas. In 2009, when we went to see the Harry Potter film from that year (it's a coincidence that they were both Potter films), there was a guy who, five minutes from the end, decided to leave; rather than going back through the building's hallways, he exited using the door near to the screen. The result? As it led directly to the outside - and as it was a hot and sunny day - he flooded the dark room with incredibly bright sunlight.

I won't deny that many people do encounter inconsiderate types at the cinema, but I've been lucky to have not come across any other than the two I mentioned above. How have your experiences at the cinema been?
