Yeah, had a dev manager that used to bring his daughter, who I'd guess to be around 10. She was so noisy and obnoxious, I seriously thought she had a mental disability, so I cut her some slack (not that it suddenly made it okay to take her to work). And then I figured out that she was just undisciplined...

That same office (which, as I'm sure you have figured out, was an open office) allowed dogs. Mostly fine, I'd take our well-trained, quiet female pit bull into the office. She'd bug me to go play around outside more than I would have liked, but was otherwise inconspicuous. But as someone else in the thread has pointed out, dogs in the office doesn't scale. There's gonna be the one (or more) dog (much like the one child noted above) that doesn't belong in an office. One lady brought her other-dog-hating dog every day. "Bark, bark, bark" every time another dog was in sight. Etc., etc.

I guess my point is, yessh people, what happened to the professional work environment?

So much this. Workplaces used to be for working. Then you could go home after 8 hours and let go. Now you spend 12 hours getting half the work done because the office is no longer a workplace but a hangout.

'I guess my point is, yessh people, what happened to the professional work environment?'

Maybe related to bullshit jobs since these people are obviously not doing any real work, just bringing their homelife to the office in order to make time pass quicker?

Mmm, possibly; I cut down to taking the dog only once or twice a week because she took a non-trivial bit of maintenance and, well, I have work to do.
