Sur la plage avec la plume de ma tante

[AuntDaisy]

My schoolboy French is not good (I'm ashamed to admit), but this sign seems a tad severe. Shared on Twitter by "Bat".

I remember reading about the Welsh sign confusion, have there been others?

Yes, but in one respect not incorrect, as it's not necessarily the depth that's the critical factor in death from drowning...
It might attract attention to the facts presented though so perhaps one positive from a mistake?
