when I got to the parking garage at work today the place was pretty full but there was an empty spot with a giant red cone in front of it lol. I was very tempted to just take the spot.
I have actually have seen this done. An under construction processing plant was having a really bad problem with supply trucks cutting one corner short and it was messing up the dirt work crew who were trying to prep for the concrete crew, they put out cones in good faith, they kept getting run over (probably accidentally at first, but the fued had been started). The dirt crew raised heck with the transport crew who then started running them over on purpose. The concrete crew got fed up with the bickering and filled all the cones with concrete, until you’ve seen it you would not believe how solidly a concrete filled traffic cone can wedge into the duals on an 18 wheeler.
