Passage: The other day , I went to Target to buy a new pair of jeans . After I found a pair that I liked , I took them up to the counter so that I could pay with a credit card . I handed the jeans to the checkout clerk .  She asked if I would be paying with cash or a credit card , and I told her I 'd be using my Visa card . I put my card into the machine so that it could read the chip . Then I pressed the " credit " button and confirmed that the total was all right .  Finally , I signed on the screen .  When I was finished paying , the cash register printed out a cash register receipt that showed how much I had paid for my jeans . Question: When did they need to pay? Option1: At the front door Option2: At checkout
At checkout
