non-recommending

Aaron and I just had a conversation about having negative reviews for books in my store. Something like ‘Employee least favorites’ or ‘Non-recommends’.
“This is insipid advice for losers. Get it for your mother in law, she needs it.”
“If you really hate someone, give them this book. They will waste at least 10 hours reading this piece of crap. That’s 10 less hours they will be bothering you.”
There are a lot of books I can not recommend.
