"Well, sir, in three months I could pass that girl off as a duchess at an ambassador's garden party. I could even get her a place as lady's maid or shop assistant, which requires better English."

People in upper class social orders have worse English than those who are members of the lower class.
People are more forgiving of errors in English if the person is in a high social class.
