I readily and proudly admit to being a plaintiff’s lawyer. And, I confess, from time to time I have taken what some would argue as "aggressive" positions on the responsibility of certain defendants to warn others of the risk of harm.
However, the most aggressive plaintiff’s lawyer on the planet would not think the warning given in the restrooms in the convention center in Vancouver was necessary. This is the language of a sign posted above each urinal.
The Vancouver Convention Centre is committed to sustainability and uses recycled non-potable water from its Waste Treatment Facility to flush toilets and urinals. This water is not intended for consumption.
