@Charles_Beliando its good to hear that you are busy
It is not recommended by FSSAI and FHRAI (In India) to serve buffet till the pandemic comes to an end. However, if the requirement is inevitable in your operation, then u have to follow the basic COVID protocol for COVID as per your country rule and also high standards of hygiene and sanitation facilities of your property and premises, especially the dining area and buffet counter.
It is preferred to have dedicated staff behind the buffet counter to serve the guest ( minimum of 1 server for 2 chafing dish is recommended ). This will avoid the guest from having direct contact with any common food displayed surface.
In short, the guest should hold his/her plate and every single item should be served by the assigned food server who must be 100% clean and perfect as per COVID protocol.
Recommended to use a maximum of disposable items to reduce the risk (eg. paper placemats , paper tissues)
Water should be pre-placed on table, waiters to be attentive and service should be provided on guest call. Unwanted contact to the guest should be avoided as exceeding the expectation in the current scenario is service “on request” - avoid additional guest contact (upselling and suggestive selling interactions should be restricted).
