We've all been there. There's a game with a shop/upgrade system, and it's given a personality or atmosphere, because of the character running it, or where the shop takes place. My personal favorites are Tatiana, Christopher, and Maury the Traveling Chef. We all know people love the RE4 Merchant, so I wanted to gush about other characters. As far as regular shops or upgrade stations: all of the ones from Devil May Cry have a unique theme and interface. I am not counting DmC's, btw.
