다시 말해 주세요 (Dasi malhae juseyo): Say That Again

Do not nod past it

The dangerous move is 네 when you heard only the last syllable. The other person will go on. A price, a name, or an exit number will be gone.

Stop the line. You do not need a grammar class in the doorway, and you do not need to explain your whole level. You need one repair.

다시 말해 주세요.
dasi malhae juseyo — Please say that again.

해 주세요 asks them to do the speaking as a favour. 말하다 plus -아/어 주다 plus 세요. It is not a boss command. It is the same stack as 열어 주세요, now aimed at the sentence you missed.

Slow, then write

천천히요 is enough at a counter. The verb is missing and everyone still hears it. The full line is 천천히 말해 주세요.

이름 다시 적어 주세요.
ireum dasi jeogeo juseyo — Please write the name again.

적어 주세요 is the polite request on 적다. Use it for a station exit, a medicine label, a phone number. Sound is the problem; paper is the fix.

한 번만 더요 asks for one more pass, not a lecture. 뭐라고 하셨어요? raises the verb and stays usable with a stranger. 뭐라고요 can land sharp. Keep it for friends.

The problem is your ear

잘 못 들었어요.
jal mot deureosseoyo — I didn’t catch that.

못 들었어요 puts the miss on hearing, not on refusal. 모르겠어요 is “I don’t get it” after you heard the words. Use 못 들었어요 first if the sound failed.

If you name a reason and you apologise, the hinge is -아서/어서: 못 들어서 죄송해요. Do not write 못 들으니까 죄송해요.

영어 할 수 있으세요? is a last tool, not the first. Try the repeat, the slow-down, and the written word before you switch languages. Many counters will already slow down for 천천히요 alone, without a longer speech.

One job: get the line said again, slower, or on paper. Pretending you understood is how you board the wrong bus.
