Sometimes at my walmart..
People have wrong coupons but will spend 10minutes arguing with cashier...then manager...then some leave all their stuff and buy nothing!! Others will make cashier go back through packed bags and take out like 5items. (Keep in mind these are not people who appear to have financial issues)**in fact, they are wearing shoes and handbag worth $200or more...so why are you haggling over walmart prices...you could have afforded everything!
