Unfiltered Story #204315

(I’m in the middle of putting books away on the shelves when a woman in her early thirties or so comes into the store and asks me to help her find a book.)
Customer: “Do you have any books by Emily Giffen?”
Me: (after checking the computer system) “It doesn’t look like we do, but let’s check in the section where her books are, sometimes the computer’s wrong.”
(I check the G section of Fiction and the New Releases wall and don’t see any of her books).
Me: “I’m sorry, ma’am, it looks like we don’t have any of her books at this time.”
Customer: “Could you recommend any authors with books kind of like hers?”
Me: (I’ve never read any of her books but I try to get some information) “What does she tend to write about?”
Customer: “Oh, just women in their thirties, kind of like me.”
Me: (I rattle off a few other authors that sound kind of close) “Those may be along the lines you’re looking for, but I’ve never read any of Emily Giffen’s books so I’m not 100% sure.”
Customer: “Well, you work in a bookstore, don’t you? You should know what the books you’re selling are about!”
Me: (as politely as possible) “Yes, ma’am, but I’m not able to read every single book that comes into the store.”
(She left a little bit after that, but what I really wanted to say was “Sorry that our book tastes don’t mesh.”)
