A human sets up a shop on board a particularly large station within Alliance space. Before too long, the person has a lot of other humans visiting their shop, especially chefs. What is their profession? Sharpening blades. And instead of using anything electronic, they have a large whetstone, a strop, and some pieces of material to test the sharpness of the blades. He's one of the best in his profession, though his alliance friends sometimes see all the blades, and get a little nervous. -- Fighting Fit
Small businesses usually have a mayfly existence in large stations, mostly because what worked in a small station doesn't necessarily work anywhere else. A bored transient can find, for example, a little hole-in-the-wall cafe that does the Alliance's best Haargin Dragonfruit Toasted Sandwich. In a station where even the people living there know perhaps two percent of the total available territory, there's almost no chances to find a little hole-in-the-wall anything.
It pays to advertise, but you have to be able to afford it first.
This little hole-in-the-wall is not leading a mayfly life. In fact, there's something of a queue winding its way towards the door. Some in the queue are curious to see what the rest are queueing for, but are too polite to interrupt a stranger's thoughts and just ask.
