There's been a measurable shift back toward independent bookstores over the last few years, and a lot of it comes down to what they offer that your phone just can't replicate. The atmosphere matters way more than people think - you walk in and there's staff who actually love books, recommendations written by hand on little cards, maybe a coffee bar, sometimes events. It's tactile and social in a way that browsing Amazon never will be, even if the algorithm is weirdly good at suggesting things.
I noticed this firsthand when a friend dragged me to a local bookshop to kill time, and I ended up spending an hour just picking things up, reading jacket blurbs, overhearing conversations about what people were reading. I came home with three books I'd never have found scrolling on my own. That experience - the randomness, the human element - is what's pulling people back. You can discover something on your phone and then want the real thing, or you can just wander in looking for nothing particular and leave with something brilliant. Plus there's this whole vibe around supporting independent shops that appeals to people tired of mega-corporations, so it becomes a bit of an event rather than just a transaction.
