가는 날이 장날 as luck would have it

A :  How did the shopping for presents go?
     선물 사러 간다더니 잘 다녀왔어요?

B : Don't even ask.
     말도 마세요.
    
     As luck would have it, it was the last day of a sale
     at the department store.I was almost crushed to death.
     가는 날이 장날이라고 백화점 세일 마지막 날이라
     깔려죽을 뻔했지 뭐예요.
