How do they define "most" surfaces?

I got an air freshener about a week ago and decided to instlal it. It is the type that sticks to the wall and you press down on it to make it spray. This is quite odd to me in the first place as it sprays right where you have to press down so you get a hand covered with air freshener.

That problem was solved by the thing breaking before I could even install it though.

Here is the kicker, however. The packaging says "Attaches to most household surfaces." and then goes on to say "Do not use on delicate or vinyl wallpaper, or bare wood. Not recommoneded for use on plasterboard or painted drywall.

So it seems that "most" surfaces refers to tile, metal and stone. I've been to a lot of houses and the places I find tile, metal and stone in those houses is floors, countertops and fixtures. None of which is suitable for the installation of an air freshener.

It reminds me of the sunscreen I get. It says in bold letters on the front of the bottle "Waterproof and sweatproof" and on the back it clearly says to reapply after swimming or sweating.

And still there aren't people out there slapping these advertising directors across the nuckles with rulers for lying (I assum because they eventually tell the truth in small letters on the back of the product.)
