"작은 불행들이 끊임없이 자신을 파고든다." => A string of small misfortunes are encroaching into one's life. "후회는 그렇게 사소한 일에서 시작된다." => Regrets start from such an insignificant thing. "인마 넌을 어디 달고 다니냐? 좀 맞자 찝찝해" ('넌을' is probably '눈을') => Hey, what have you got your eyes for (that you miss such an obvious thing)? (좀 맞자 찝찝해 is unclear. 맞다 = take a beating, 찝찝하다 = have an unpleasant sense of something unresolved) "됐다, 이제 나오지 마. 사정 딱해서 뫄줬더니 안되겠어." (뫄줬더니 -> 봐줬더니) => Okay, don't show up anymore. I took you in seeing the trouble you were in, but not anymore. (나오다 can be "to come out" or "to report to work" - it appears to be the latter here.) "하여튼간빠져가지고선... 손님들 있는데 꼬라지 하고는" = 하여튼 간(에) 빠져 가지고선 ... 손님들 있는데 꼬라지하고는. => Whatever, you've fallen head over heels in it... and look at that awful look with customers around.
