Seriously peeps, watch out mmmkay?

So I'm back at work today. There's a lot of tradies around because the building is undergoing a variety of system works; pipe replacement, putting in new network cables etc., so there is a degree of ladder dodging and the occasional safety bollards and orange danger signs. But today took it to another level.

In the hallway of my office to the internal stairs, I saw these bollards. Nothing particularly special about them.

Until you get closer and you get to see what the danger is.
What the...?! Putting men in confined spaces?! Damn straight we'd better be careful because forcing those guys into small workplaces makes them angry!
And you won't like them when they're angry...
