Next time you buy veggies or fruits , have them bagged and weighed before you come here .   Sorry . I didn't know .   The total comes to US $ 65.81 . How will you pay today ?   I'm going to use my ATM card .   Slide your card through the card ID pad and punch in your PIN .   Done .   One moment . Do you want to withdraw some cash while you're at it ?   No , thanks .   Paper or plastic ?   Pardon me ?   Do you want paper or plastic bags for your groceries ?
