Im sorry I left without you last night, but I told

Im sorry I left without you last night, but I told you to meet me early because the presentation started at 8:00. I had worked / had been working to get it right for years, and I didnt want to miss the beginning. By the time I finally left the cafe where we were supposed to meet, I had had / had been having five cups of coffee and I had waited / had been waiting for over an hour. I had to leave because I had arranged / had been arranging to meet Katherine Stern in front of the gallery. When I arrived, Katherine had already come/ had already been coming inside and she was talking to the first guests near the entrance. She was really angry because she had waited / had been waiting for more than half an hour. Katherine told me you had been / had been being late several times in the past and that she would not make plans with you again in the future. And in the future, I suggest you be on time!
