How does one get into a job at a Mom and Pop shop?

I wanna work at a smaller company where it's just me and some old lady dottering around the shop all day, you know? A book store, an antique store, a textile shop, that sort of thing, just that really nice kind of place, but I can't seem to find them online and I don't know how to get into them otherwise. If y'all know any of that kind of store hiring, or know how to find them to apply, I would really, really appreciate it.
