YES! (Well, not actual LEGISLATION, but it is just SO wrong!)
And those signs on the backs of SCHOOL buses that say, "Driver's Wanted"!
Ditto with company names that are misspelled or just plain stupid--like "HOM Furniture" (Twin Cities, MN, USA furniture store -- I'll never go in it) and "RE/Max" (a real estate chain I'll never use).
Also, with mis-pronounced names, like the Toyota Prius, which they insist on mis-pronouncing "pre-us" instead of "pry-us", as is the correct pronunciation (triumph, trial, pious, private, primate...)--look it up in the dictionary, eh?
And road names--Chicago (I used to live there), WHY do you pronounce the road "Kirchoff" as rhyming with "kerchief"? Haven't you taken physics class and learned of this famous scientist, whose name is pronounced "kirk-off", as in, a German pronunciation? And what's with the town "Des Plaines" (which you pronounce "Dess planes")? We don't say, "Des Moines" Iowa that way--it should be "De-plain", I think (I speak no French--I'm German, as you can guess from my name).
And town names. Minnesota, "Faribault" is French--it's pronounced "fair-i-bow", not "fair-bolt". And, "New Prague" does NOT rhyme with "New Plague"--"New Prog", please, like the beautiful country it's named for! And many apologies to all of the Native Americans whose town and road and other names we mispronounce horribly out of total ignorance of your beautiful languages.
Colloquialisms are a pain, but should only be outlawed by editors in appropriate contexts. Public education and re-education should cure us of "ain't" and "drive-thru" and "alot" and other such atrocities.
