Topic: Buying Food
One day, I quickly ran to the market to grab some grub(food). I slowly grabbed the bag of chips from the isles and happily skipped to the counter. The cashier quietly awaited for the payment. I furiously looked into my pockets for my money. Quickly scattering my pockets I've come to noticed I had no money. I quickly raced outside the door, throwing the food on the floor. I sadly cried thinking how i lost my money.
Hope this helps, made it on the spot :)
