Do they even know it's wrong?

Many long term residents of Hong Kong have remarked on the deteriorating standard of English in the territory that likes to proclaim itself "Asia's world city". Wellcome supermarket continues to display posters in some of its branches exhorting customers to "Use less plastic bags". Good idea, but as someone pointed out several years ago, shouldn't there be a companion campaign educating the public to "Use fewer water"?
