Former Apple Genius Stephen Hackett recounted his years working at an Apple Store in his recent book, Bartending: Memoirs of an Apple Genius. The short book is just under 50 pages and details the customers and problems Hackett saw while working as a Genius.

It's a lighthearted, personal read that you can finish in about an hour. The book is available for US$8.99 from Hackett's website in an iBooks-friendly ePub format and from Amazon (that's Steven's referral link, so he'll make an extra few cents) in Kindle format.
