Raul:No need. This store has self-checkout machines.
Claudia:I don't know. I think it would be easier going through a cashier line.
Raul:Using the self-checkout will be much quicker. Let me show you.
All you have to do is scan the barcodes on each grocery item.
Claudia:There are no barcodes on fruits and vegetables.
Raul:All you have to do is put them on the scale and find the product on the touch-screen.
Claudia:You look. I'll start bagging.
Raul:Wait! You're supposed to wait until everything is scanned before removing items from the bagging area to put in bags.
Oh no, now there's a “see attendant” message on the screen.
Claudia:What do we do now?
Raul:We wait for the attendant to clear the error and void the transaction. Then we start again.
Claudia:Great. You're right. This is much faster.
Raul:It is if you know what you're doing.
Claudia:I'll tell you what. I'll take half of our groceries and stand in line and you use the self-checkout.
We'll see which is faster.
Raul:That's a sucker bet. I have no doubt that I'll be done before you are.
Claudia:I'm not worried. The last one out the door makes dinner.
Raul:You're on. Just remember that I like my steak well done.
