They used to meet you on arrival and arrange everything for your stay. Now they find valued jobs as Concierges in up-market hotels. The person who knows where to find experts and enthusiasts for Films and Docos. Inspired by a Thomas Cook employee who used to greet VIP's and smooth their path. -- Knitnan
Some people are best at connections. They just... know people. They know another individual who might have the knowledge of the thing. They know a person who knows a person. They network, and hoard interesting people with equally interesting niche knowledge like a dragon may hoard gold and gems. They gleefully connect the people who want to learn with the people who already know.
Some people are best at finding sources. Where to get that esoteric fiddly bit that is apparently not made any more. Where to find the best examples of some species' delicacy. Who creates those marvellous little art pieces and why they leave them in seemingly random locations. If you want to find something, if you want to know the best place to get them at the most competitive price, if you're willing to pay for it to be made custom... these are the people who help you.
Rarest of all are the people who can do both. They are a beacon of friendly help, a central repository for local knowledge. They know a person who knows a person... they know where you can get that. They are the rock upon which the pillars of community lie. In the Galactic Alliance, they are known collectively as Aunties. It is not a blood relation honorific. It is a title. Those concerned with their gendered variant can also choose from Uncle, the masculine version, and Unty, the agender version. Some folks just can't be stopped from being specific in that one aspect. They know what to do to help almost any problem, and if they find themselves temporarily foxed, they know how to network.
