I was laying a concrete floor & my day-old phone slipped out of my top shirt pocket straight into the wet concrete
I put a sheet of cardboard over the long-drop hole and said to my workmate “wouldn’t it be funny if someone fell in the hole!”.
I'm peeling a shutter off and got one hell of a fright as looking directly at me from within the concrete column is one…
For some reason I stepped into the 3 level lift shafts and shut the door and couldn't open it again as there was no power and the manual emergency system didn't work.
I checked the floor, and there was the cow, the large steel wheel and the calf wandering throughout the freshly laid floor, dropping lots of cowpats along the way.
It took us two hours to chip our way through to get our concrete covered gear back.
