Yesterday I was in the biggest shop in one part of the city. The shop was very large, and was more choice. The staff was very sociable, and I thought that the quality of the products must be of good quality. I needed to strawberry milkshake. Of course as soon as I went to pick berries. There were two large shelf with berries, and I took one box, which was strawberry. Prices were low, from what this store interested me the most. When I got home, I washed my hands and prepared all the ingredients for a milkshake. I threw the berries into the milk in the blender and turn on the mixing products. Once I opened the lid of the blender, I noticed some gray brown spots. I decided to cut in half the remaining berries and then horrified at all the berries turned worms! Please remove the product from store berries, and bring me the money.
