Note: This is a repeat of a blog post from several years ago when the blog wasn't totally dedicated to books and book related things. It is book related though.
One of my most embarrassing hearing mistakes so far happened when I was working as a book clerk at Media Play years ago.
A woman and her teenage daughter came in when it was almost closing time. So, the book department was pretty much empty except for me and my ride home. The woman approached me at the desk and at the time we had a pocket size guide to sexual health that some company was pushing for the holidays on the counter. She glanced at the book and then asked me for what I thought was the Kama Sutra. I was thinking, "Wow. She must have some open relationship with her daughter if she can look at a book like that with her in tow."
I didn't repeat the title like I usually did. I just walked her over to the section and pointed out where the Kama Sutra books were. She looked at me blushing and puzzled. It dawned on me. I said, "That wasn't what you asked for, was it?"
"No. The Campbell's Soup book. The cookbook."
I was thoroughly embarrassed. At least she wasn't totally offended and I knew where the book was that she wanted. So, she walked out a satisfied if slightly embarrassed customer. And I lucked out that she wasn't offended enough to complain to management about my showing her and her daughter books on sexual health when all she wanted was as cookbook.
After that I learned to repeat back whatever title people gave me before I showed them the book or search results. Didn't totally stop mistakes, but it lessened the really embarrassing ones.
