Hi . I'm looking for a gift for my niece .   Well , little girls seem to love Barbie dolls .   That's perfect . I want to see one .   Here you are — she's called Digital Barbie .   Oh , I like Digital Barbie ! How much does she cost ?   This Barbie is only $ 29.95 .   That's perfect . Let me have her .   Very good . Is there anything else you would like ?   No , that'll do it for now .   Including tax , your total will be $ 32.42 . Cash or charge ?   Let me give you cash , please .   Here's your change and receipt . Thank you .
