Not my experience at all, seems to be just about anyone can be an asshole.

I was in the library for the first time in ages, two of them actually. Mixed group of people, pretty busy. I am happy to say I heard not a single notification or phone ring the whole time. I hadn’t thought about it until you mentioned it. That was kind of refreshing. Unlike waiting rooms, the bus, coffee shop, the quiet lounge at the airport. Maybe I got lucky.
