You decided to get the pool, since you wanted to relax this Summer, and what better way of doing that, then relaxing in an inflatable pool you were about to inflate, and fill with water from a hose. So, you took the box with the pool inside, and take it over to the cash register, so you could place it in a bag.
The cashier, who was wearing a coconut-bra, hula-skirt, and a bunch of flower crafted jewelry price checks the pool in the box you got, and placed it in a bag for you after you paid for it with the money it was worth. Once the pool in a box was purchased, you take the bag it was in with you, and then leave Change-Mart, while riding on your bike back to your house. With the pool you now had, you head into your backyard, and inflate the pool, while at the same time filling it with water.
