Signs I'd Like to Hang on the Break Room Door

There's a sign I'd really, really, really like to hang on the break room door. 
It would read a little something like this...

"Please do not reheat any meals containing fish in these microwaves. 
The smell will linger for hours (and possibly days), and will make poor preggos gag every.single.time they walk in. Thank you!"

Would that be totally wrong to do?

(Please say that it would be okay.)
