May I help you ?   Yes , I would like to return these slacks .   Alright . Do you have your receipt ?   Yes . Here it is . I bought them last week .   And why are you returning them ?   I bought them to go with a blouse of mine . But they don't really match .   I see . Oh , wait . Ma'am , I'm sorry . These slacks were on sale .   Yes , they were thirty percent off .   I'm sorry , but we don't allow returns on sale items .   I know many stores have that policy . But I have returned sale items here before .   I'm sorry , but we usually don't do it . It is our policy .
