“kekkou desu” or “daijoubu desu”：Which is Much Stronger to Refuse?
Which words do you use in refusing an invitation, “けっこうです(kekkou desu)” or “だいじょうぶです(daijoubu desu)”? Although the meaning of both is the absolute same meaning, one of two is more polite than the other. Let me introduce the meaning of both and which one is the more polite way to refuse today!
No thank you. / 不用 / 괜찮아요 / Đủ rồi
“結構です” means “No thank you.” and which has been for people who refuse an invitation. “結構です” sounds pretty unfriendly and stronger. So native speakers feel that people saying “結構です” might’ve got a little bit angry in people using it. However, if you FRIENDLY say “結構です”, you would be just polite. If not, you would be rather impolite. You should be pretty careful to use “結構です”. When using this, you have to be smiley.

もう少しコーヒーいかがですか？ (Would you like some more coffee?) (要不要来点咖啡？) (커피 더 마실래요?) (Bạn có muốn thêm cà phê không?)
いいえ 、結構です。 (No thank you.) (不用了，谢谢。) (아뇨. 괜찮아요.) (Không cần đâu, tôi đủ rồi.)

I’m good now, thanks. / 没关系 / 괜찮습니다 / Không cần đâu
“大丈夫です” means “I’m good now, thanks.” and which has been also used for people who refuse the invitation. “大丈夫です” is the basic refusing word for the invitation. It’s not impolite and you shouldn’t be careful whether you’re saying it friendly or not. So, “大丈夫です” is the better use to refuse it. Native speakers often use this in daily conversations “あっ、大丈夫です。” like this. Somewhat adding “あっ” before “大丈夫です。”, that would be pretty polite than only saying “大丈夫です。”.
