Our local library layout means you walk through the public computer access area to get to the children's section.
Leaving the library this afternoon with my two DC, I saw a man on a computer looking at explicitly sexual pictures of women. DC didn't seem to notice. The computer was right next to the main walkway through the computer area and the screen was visible from a good distance away. The screen was on a pedestal which you stood next to to use. I got a bit of a shock, and went to a librarian and told her what I'd seen. I didn't hang around as we were leaving and were with friends (they didn't see the screen).
I phoned them later to ask what the outcome of the situation was and they said they can't give me any information.
AIBU to find that strange?
