Tilemen, charge those customers for full extend. They spend thousands for materials. And when they are talking to you, they pretend that they are poor and miserable and want to pay you couple hundreds for labor. Let them pay thousands to you or let them do labor by themselves. Do yall sick and tired to work for food and gas yet ? Don't be a victim of this so-called "uncertain economy". Those who are paying thousands for a glass tile are pretty much "certain" about their income.
