Why doesn't Richard receive what he was promised at Mr. Crane's company?

Griggs obtains Richard a position as an intern in an optical shop. The boss of the shop, Mr. Crane, is a Yankee and hires Richard immediately. Reynolds and Pease are two white men who work in the shop and cause nothing but trouble for Richard, who truly wishes to learn the trade. Both make degrading racial comments in front of Richard and threaten to kill him for failing to call Pease by "Mister Pease" (even when Richard had not forgotten). Richard leaves the job out of fear.
