I blogged a sign last month warning wearers of Crocs about the peril they face.
Apparently it’s not just a Canadian thing.
This picture was taken in Hong Kong, and was sent in by Julien Bissonnette. (You can see other Hong Kong signs as shot by Julien here.)
The sign says:
Mind your toes.
Ensure that children in your care keep their feet well clear of the step edge especially when wearing plastic shoes or sandals.
No mention of Crocs, but the image accompanying the words is pretty clear.
