Do you really need to be told how to use the restroom

I get a lot of newsletters. Mostly from sites where I sign up and get placed on the mailing list. I am a member of several travel sites and I read their letters often.

This past week, on of my letters focused on how to use the restroom. I mean, who doesn't know this stuff. Most of it was common sense. In my opinion that's the easiest way to tick off a reader. That's by making the simplest of things look complicated. It's an insult to your reader to treat them like idiots.
