Why do people keep throwing up on Zoo Tycoon?

In Zoo Tycoon, visitors may throw up due to a variety of factors, primarily related to their happiness and the environment. If the zoo is dirty, overcrowded, or if animals are in distress, it can lead to dissatisfaction among guests. Additionally, seeing animals in poor conditions or having inadequate food and restroom facilities can contribute to this issue. Managing these aspects effectively helps maintain visitor satisfaction and prevents them from becoming sick.
