Once upon a time, there was a cat named Bernie who lived in a small house with his owner. Bernie was a very picky eater and his owner had to be very careful while feeding him. The owner had to buy the most stringent and expensive cat food to make sure Bernie ate well.
One day, while the owner was away, Bernie managed to escape through the window and wandered off into the streets. He was very hungry and started to meow loudly in search of food. A kind lady heard him and offered him a piece of fish she had just caught. Bernie sniffed it and realized that it wasn't stringent enough for his liking. He politely declined and continued his search.
As he was walking, he stumbled upon a restaurant that had just opened. He walked in and saw a plate of fish that looked very stringent. He asked the waiter if he could have a piece and the waiter obliged. Bernie licked his whiskers in delight as he ate the fish.
From that day on, Bernie would sneak out every now and then to that restaurant to have his favorite stringent fish. His owner never found out about his secret outings and Bernie lived the rest of his life happily enjoying the stringent fish.
