For me typically some attribute remains in memory after the name fades: "white-teeth marketing dude" or "guy obsessed with keyboards". I suppose that's how names started: Miller, Shepard, etc. As a corollary to this if I'm going into a business situation where I think it would be useful to be remembered, I'll try to wear something notable -- brightly colored shoes, something like that. Imagining the other parties discussing "that bloke, what was his name?? who? Um, the one with the orange shoes. Oh yes".
