Those who are saying the cash register processes the Coupons, not the individual cashiers, are correct. This is all programmed into their system, cashiers do not make any decisions about what gets discounted and what does not. There are so many limitations and policies related to discounts, coupons and honoring other stores' coupons etc it would not be possible for a cashier to keep it all straight-they don't get paid enough to bear that burden!!!!
