After a long time

I went to see a movie after work. It was an anime, and it was a late-night screening. I thought the entrance was crowded because of something, but then I saw a few groups of people arguing because minors couldn't enter this late screening without a guardian. They were checking the birth dates of people who looked underage. Wow, surprised me. They didn't check me at all, though, which is understandable given how I look, right? Among those leaving to get refunds, I heard one person say to their companion, 'They should have told us from the start...' But I bet it was mentioned somewhere in writing or something. At least the online purchase site has a notice about 'age restrictions,' and I rarely buy tickets at the theater, so I don't know for sure, but it's unlikely they wouldn't mention it, right? It's a ticket machine, not a person selling it, so there's probably even more information written. Maybe they were disappointed, but is it cold of me to think it was their own fault for not checking? Well, if you can buy it, you buy it, right? That's probably why so many people were asking for refunds. It doesn't concern me, and I had fun, so no problem.
