Martin and Jane were shopping. They were in Ross Dress for Less. They had just bought shirts, pants, skirts, and tops that filled up four plastic bags. Martin picked up all four bags. Jane said there was no need to do that. “Why not?” he asked her.

“We can just put everything into a Ross cart and roll it out to the car,” she suggested.

“We can't do that,” he replied. “These carts are for in-store use only. You can't walk all over the mall with their carts. Let's just carry these bags out to the car, put them into the trunk, and then we can continue to shop.” They no sooner walked out the door of Ross than they saw about 50 rental shopping carts locked to a rail.

“See,” Martin pointed out to Jane, “if you want to use the cart, you can just rent one for the whole day from the rack.”

The mall was huge, and it was air-conditioned. Both of them were chilly. "When we get back to the car, let's grab our jackets," Jane suggested. As soon as they walked outside, the blast of summer heat hit them. Once at the car, they put the bags into the trunk. Then they plopped down into the front seats. They were both tired from all the walking they had just done. When they felt more refreshed, they locked the car and walked back to the mall entrance.

"Wait a minute," Jane said. They stopped. Jane told Martin about the two suspicious characters sitting outside the entrance. "They were watching us as we carried the bags out to the car," she said.

"You have very sharp eyes," Martin said. They went back to their car. Martin drove around to the other side of the mall, and they parked in the area marked “6.”
