There are 5 times when you cannot eat pizza: 1. At wedding ceremonies, as Indian cuisine is typically served. 2. At Indian restaurants, though some may serve Indian-style pizza options. 3. In the car, as pizza can easily be eaten in the car. 4. When your friends don't like pizza, though true friends should share tastes. 5. The document does not provide a 5th scenario, and instead advertises Pizza Hut.
