Lou's' Bartender

Lou was the bartender of Lou's Bar in Gotham City.

Lou served Michael Wuertz a shot when he visited off-duty. Wuertz obviously didn't like Lou who proceeded to ask questions reguarding why he wasn't helping out with the trouble outside.

As the bartender made his excuse to go to the restroom, Wuertz heard the back door open again and assuming it was him again, snapped; "Now, what? You need someone to shake it for you ... ?!" Only it wasn't Lou, but Harvey Dent/Two-Face who was furious at him for being responsible for Rachel's death in an explosion and eventually shot Wuertz.

It remains unclear if Lou was illicitly killed by Dent on his way to the restroom or just taking some time.
