One day our family went to Super Bazaar. We bought a few things and as we were returning we had to go through a checkpoint. Suddenly, when my sister was walking through it, it started making a noise. Then the staff at the store made her walk to and fro through the checkpoint. My father got angry on seeing this and asked them what they were doing. They told us that the machine had found a price tag. Then a man standing near to us spotted the price tag which was stuck on the sole of her shoes. While we were returning home we all had a hearty laugh.
