today at work I was so tired that when I went to the bathroom I fell asleep on the toilet "오늘 (나는) 직장에서 너무 피곤해서 (나는) 샤워실에 갔고 화장실에서 잠들었다" 회화체 - "오늘 직장에서 너무 피곤해서 (bathroom 생략) 화장실에서 잠들었어!" One time at work I was so tired that when i went to the bathroom I feel asleep on the toilet One time "어느 때" in dictionary but "어느 때" is naturally "저번에" or "언제 한번" in this sentence. "저번에 직장에서 너무 피곤해서 (나는) (omission bathroom) 화장실에서 잠들었다"
