What is expressly prohibited for drinking purposes in establishments?

The prohibition of common cups in establishments is rooted in health and safety concerns. Common cups are typically shared among multiple users, which increases the risk of cross-contamination and the spread of illnesses, especially in environments like restaurants or public facilities. This practice fails to align with sanitation standards that aim to safeguard the health of patrons by minimizing exposure to harmful bacteria and viruses that can easily be transmitted through shared drinking vessels.

In contrast, plastic water bottles, reusable straws, and drink vending machines can be designed to be used in a way that supports hygiene and safety. Plastic water bottles can be single-use or sanitized, reusable straws can be cleaned thoroughly after each use, and drink vending machines provide individual, sealed beverages that reduce the risk of contamination. Thus, the focus on eliminating common cups helps ensure a higher standard of sanitation in public establishments.
