For the sake of safety, many restaurants have begun to take sanitary measures to reassure customers, and masks are one of them. Masks can at least block invisible bacteria, saliva foam and so on. It also gives some comfort to the "nervous" diners now. However, masks also have their own problems. Today, when "smile service" is advocated, a piece of non-woven fabric directly covers half of the face and only exposes the eyes. Even if you smile like a flower, you will be embarrassed. In the restaurant where 1 uses transparent masks, the waiters still greet everyone with a smile, but after a closer look, they all have a transparent half-moon plastic sheet on their faces, which is a sanitary transparent mask produced by Yimei Catering Company, replacing the traditional white mask. And his greatest advantage is that the service staff can communicate with the guests better with a smile. In fact, not only the catering industry, transparent masks can also be applied to hospitals, supermarkets, beauty services, etc., so that service personnel can show more smiles and make contact healthier.
