반말? 존댓말?

Hoya 說 카드로 계산할게.

Sori 說 카드로 계산할게요.

The staff are strangers, so the ending stays 해요체. 계산할게 (without 요) is casual speech for a friend — easy to slip into right after talking to Bori.

Hoya 說 ㅇㅇ 알겠어.

Sori 說 네, 알겠어요.

Sori-ssaem is your teacher, so the ending stays 해요체 with 요. ㅇㅇ and 알겠어 are for a friend you speak casually with, even in a text.

Sori 說 계좌를 만들고 싶은데요.

The clerk is a stranger: use 해요체. 싶어 is 반말, for Bori; at a counter say 싶은데요 (or 싶어요).

Hoya 說 일요일에 놀러 갈게.

Sori 說 일요일에 놀러 갈게요.

She speaks 반말 to you because she is older. You are younger and she is your friend's parent, so you answer in 해요체 — and you keep it. 반말 (갈게) is for Bori.

Hoya 說 빨래방 오른쪽이야.

Sori 說 빨래방 오른쪽이에요.

You kept the ending you had just used with Bori. The ending follows the person you are speaking to now: Bori gets 반말, the rider gets 해요체.

Hoya 說 안녕히 가세요.

Sori 說 안녕히 계세요.

You say 가세요 ('go well') to someone who is leaving, and 계세요 ('stay well') to someone who is staying. You are leaving and the clerk stays, so you say 안녕히 계세요.
