Dsw Rewards Card Does Signing Up For A Store Rewards Card Help Cashiers?

Does signing up for a store rewards card help cashiers? - dsw rewards card

It seems that almost everyone in the store in those days, these tickets for free prizes. As DSW, American Eagle, CVS, boundaries .... does not seem much. But I wonder if the cashier has committed to bringing people together or to help in any way? Because if I would not be required to sign and help us. But if there is nothing for them, I do not subscribe.
