I pay 6€ for cinema tickets and just don't buy any snacks and drinks. The fact that you can't pause the movie, or check your phone, is worth it for me, I just get distracted too easily when watching movies at home. And ads are easy to avoid by just showing up 20 minutes late.

I do avoid big Hollywood productions mostly though, and try to stick to indie productions or documentaries.

The only major annoyance I have is that I frequently get patted down because they assume I'm smuggling in my own food from outside
