Extra words...What I really need are some extra words.

I've been hanging on to this little beauty for a while because I hadn't quite decided if it was a grievous enough error to be considered a disaster.  But I've decided to go ahead with it because of the enthusiasm in the last line.

You probably realize that the phrase, "the usage of," really irks me because it's such a glaring example of how not to be concise.  It's not technically grammatically incorrect, but stylistically, it gets low marks.

What I really love, though, is that Management is apparently the cell phone abuser.  Why else would the sign so enthusiastically thank Management for refraining from using his cell phone in line?
