Good bookstores employ people who've actually read widely and can talk about what they stock with genuine knowledge rather than repeating publisher copy. They maintain reasonable inventory turn—not so much that popular titles disappear before readers know they exist, but not so little that the shelves feel picked over. They handle online orders competently: accurate listing information, fast processing, proper packing. They understand children's sections thoroughly, keep current with what's actually published versus what became a classic ten years ago, and know the difference between recommending a book because it's popular and recommending it because it suits someone's actual taste. These details separate places you trust from places you avoid.
