I planned to go to the shopping centre all week. Finally it was shopping day. I dressed comfortably, made my shopping list and grabbed my purse.  On my walk to the shopping centre  I thought about all the things I would buy. Most of the things on my list were items I needed. A tooth brush, some bread, pencils, socks. I had clipped some coupons and knew I would save a few dollars so that I could get that new game I like. I couldn't wait to see it on the shelf and actually hold it in my hands. I arrived at the shopping centre. It wasn't very busy and I was glad of that. First I did all of my important shopping. And sure enough I had enough money for the game. I rushed to the electronics section and sunk in despair when I saw the shelf was empty. They were sold out of the game I had waited so long to play. The store clerk saw my disappointment and offered me a rain check for when they got more stock in. It would be about 2 weeks' but there was hope. I gathered my things and went home. I marked my calendar for when my next trip to the shopping centre would be... in two weeks. Now all I could do was wait... patiently of course!
Who paid for the purchases?
