잘 못 does also mean "These days I don't.." I was watching a korean program when one of the MCs said to one of the guests: 한우 잘 못먹어요? In the english subs they translated it as "do you not get to eat beef often"? And that is what confuses me. I know that "잘 못" can be used along with verbs to take the meaning of 수영을 잘 못해요 (I'm not good at swimming/I can't swim well). So can someone please tell me if it has more meanings? And I remember also that some days ago I was talking with one korean friend that likes to drink alcohol. We were joking around and I suddenly asked him if 오빠는 요즘 술을 마싰죠? And he answered me: 아니요. 오빠는 잘 못마셔요. I assumed that he wanted to say "I can't drink alcohol well "(maybe because he had stomachache or something) But I just realized that maybe I interpreted it in the wrong way and what he really wanted to say was that "I don't drink alcohol since time ago". 이 두 문제를 대답하면 정말 감사할 것입니다!
