I mean, my comment might be similar to MJ's in many ways! My bar-tending and more social folk are ones she might meet in a social-ish setting: Waverley, Ryder (as a bartender), Ashley & Koa. Mariana's a performer at Midnight, so they might meet there when she's doing waitressing on the floor and stuff.
We'd probably have to do random interactions for most of the rest of mine, but Billy's in law enforcement so it's possible that they'll professionally cross paths every now and then? :D
