Please check the following paragraph.
My brother works in a car wash. He washes and cleans cars for the guests. He works hard, and my family thinks he should get higher pay. But his boss won’t raise the pay for him. Why? His boss says, "If there is a high-end car, like Mercedes or BMW beside him, he will distract his attention and can't concentrate on working. So I don’t give him more pay.”
