What is Mr. Wemmicks treatment of Mike?

Mr. Wemmick is a bit rash with Mike, you might even say rude. There is definitely a touch of superiority about him when he deals with Mike.

‘Go and wait outside, Mike,’ said the clerk.

I began to say that I hoped I was not interrupting - when the clerk shoved this gentleman out with as little ceremony as I ever saw used, and tossing his fur cap out after him, left me alone.
