Explanation
In Thailand, refusing food offered by a host, especially during a family meeting, is generally considered impolite because it can be seen as rejecting the host's generosity and hospitality. However, if you have a valid reason (e.g., dietary restriction or fullness), it is acceptable to politely decline with a smile and a soft explanation, such as 'I'm very full, thank you.' The key is to avoid a flat 'no' and instead show appreciation for the offer.
Local Tip
If you must refuse, place your hand gently on your chest and say 'Khop khun kha/krap, aroi mak, but I'm full' with a warm smile.
