Because Koriko is a large island with an equally large variety of places to work - for example, just saying your character works at a tea house when there are might be fifty tea houses isn't helpful - we're considering the best way to compose a directory. We also do not want people to feel compelled to pick the same spot to work, although they could. There are simply so many places to work that co-workers might actually be rarer compared to "people who share the same occupation".

But because it would be useful for plotting purposes as well we are discussing the best way to handle such a thing.
