Confined space

I was amused by this footpath message. There was no obvious sign of ingress to the reputed confined space, so a permit would have made no difference at all. As for danger, well really, how dangerous could it be? They didn’t even spring for red paint! As it turned out, the same stencilled words appeared along the road at regular intervals, and I was just lucky enough to find the hatchless one first, posing as a piece of street art.
