Exra gift

I went to a book store to buy a magazine. I couldn't decide between two magazines. After all I bought the magazine that had an extra gift with it. I went to Mcdonalds for lunch. I ordered the new hamburger. Then I received an Eco bag that came with the hamburger. After lunch, I went back to my office. I talked to my florist friend. She had a lot of plastic vases. I asked her what they were. She answered "I will give these as an extra gift to the customers who will buy flowers". If you get an extra gift when you buy something, you will be more happy than getting nothing.
