The first draft they send highlighted grammar errors with a red pencil. After that I'm sure it's just stacking up somewhere. It's a waste for sure, but changing the system is a long process.
What I've learned is to always include a few token spelling and grammar errors in the first draft of anything so reviewers feel like they have done their job. /s
I used to run a pizzaria and the health inspector would stick around for ages, because he couldn't find anything to site me for. I combed through the specs and found something to keep him happy. It turns out to be a minor NY health code violation to store clothing on the same storage unit as food. So I attached a coat rack to the shelf that held sealed canned good. Problem solved.
