How do the other characters react to Bartleby?

The narrator finds Bartleby to be hardworking and sedate. He also finds Bartleby's refusals to follow his instructions to be disconcerting. At first, the narrator is too busy to deal with Bartleby's conduct. As the story progresses, he consistently pushes off a confrontation.

But he wrote on silently, palely, mechanically.

a wonderful manner touched and disconcerted me.

Ginger Nut thinks Bartleby is "luny".

“I think I should kick him out of the office.”
