You must go in with it in mind that workers are trying to make a comission. They will lie and do anything to make a higher comission, even if that means vouching for a product that they know does not work. This is especially true for Andrew, as he knows what he's doing. He's there to sell a product. Even if that means lying, which obviously he does not care to do if he knows he can make a sale. Would not go back knowing I have to deal with a liar.
