- They could have an computerised lookup of location that isn't AI based very easily. It's just a stock location database.
- Shops move their stock around to get you to search the store and drive sales of other items " you didn't know you wanted".
My biggest experience of this is that those systems just aren't updated. So they will have rearranged a bunch of stuff and now the website is wrong. When they're doing it right, the same system that generates the printouts to tell store workers where to move things is also connected to the site. But there's still errors. An AI isn't going to solve that in any meaningful way, you just need to pay someone to check the locations of the top 100-200 selling items. Or niche items or whatever works to reduce the number on enquiries. It's pawbably much cheaper to do that once a month, or once every three months, than pay OpenAI for a huge contract. Have that person rotate through all the stores in a region. But that would be too bloody smart for a business to do.
