Okay, I'll just let you browse......

Customer: Do you have technical books?
Me: Sure. What kind were you looking for?
Customer: I don't know - I'll know when I see it.
Me: Okay, but what subject matter? Technical books about welding or machining or woodworking or computers? They're in different areas.
Customer: I'm not sure.
Me: Ummmm okay, well that whole area over here is non-fiction....


I completely get the "something will jump out at me" school of shopping...... But how can you not know if you're looking for a welding book or a book about computers?
