So, I work in a public library that is HEAVILY used. On a typical day every available table and study room is full to bursting with people using our electricity and free wi-fi. We average 500-800 people visiting a day and considering how small our building is, well, it always feels full.
Right now, (not quite 3 p.m.) all of our public PCs are full and there is a waiting list. A middle aged man just came in and powered up his laptop and while he was in the process of plugging in the power chord, before he even signed on, the DVD or streaming video he must have been most recently watching, started to play.
As I said, he hadn't unlocked the computer, so there was nothing was running on his screen, but the sounds of orgasm filled the air at high volume.
When I approached the man and told him that this was not an acceptable noise level for the library he did the usual song and dance..."I have no idea what that was."
