ご飯を食べていて、お代わりいかがですかと聞かれたとき。
Would you like another seving/helping?
2回目のお代わり、3回目のお代わりは
Would you like seconds?
Would you like thirds?
となります。
おなかが一杯で断るときには、
①No, thank you. I'm stuffed/ (so) full.
thanks.
②No, thank you. I couldn't eat another bite.
thanks.
③No, thank you. I can't eat another bite.
thanks.
と言います。①→②→③の順番に使用頻度が下がります。
