I work in broadcast engineering and I get calls 24/7/365 because broadcast TV is always on. I will get a call at 3am on a Saturday that something isn’t working and they need it for the morning show that starts in an hour and a half. I will get up, drive into work, walk up and ask them to show me, and It works just fine every time. People will tell me that things only work because I’m there. I think they are a little more careful stepping through procedures because I’m standing there looking like I’m about to kill something.

The 4chan Captcha never worked for me, so I stopped trying years ago. I used to go there to troll trolls when I was in a mood.
