As any retail or service worker will tell you, customers can be irrational, demanding, abusive, and brain-scramblingly, mind-bendingly strange. They can also be kind, thoughtful, funny, and full of pathos. Something about the often-fraught interaction between customer and worker, with the dividing line of the counter between them, loosens inhibitions, and has a kind of hot-house effect on eccentricity.

In I Can’t Remember the Title But the Cover is Blue, veteran bookseller Elias Greig collects the best, worst and downright weirdest customer encounters from his years working as a Sydney bookseller. From ill-behaved children to nostalgic seniors and everything in between, this hilarious and unpredictable book is the perfect gift for anyone who’s ever been on the wrong side of a counter.
