Self Service sneeze guards, also called Buffet sneeze guards, shield the displayed food while still allowing the customer access. Full-service sneeze guards, also called pass-over sneeze guards, prevent the customer from contaminating or accessing the food displayed. The top shelf contributes to the overall shielding of the food and provides a surface for the server to pass the food to the customer. The top shelf allows the overall height of the nsf sneeze guard to be reduced, which facilitates the verbal exchange between the server and the customer.
