Miscommunication

This past summer I worked at a spa. We had one treatment for couples called the Riverbath. As spa attendants we were required to set up the Riverbath and have it ready for the couple to retreat in 30 minutes prior to their couples massage. One day at work there was a huge miscommunication. I was just arriving when this was all happening, but there was three other female attendants there. Each attendant thought the other was preparing the Riverbath, but they weren't. It was almost time for their massage to start a therapist noticed that there was no one in the room for the River bath. She came and told the attendants and we had to fix the problem. Because of this communication we had to talk to the couple about what happened. We then had to ask them if they would mind having their Riverbath after their massage. Luckily they were a very understanding couple and said that was okay. There was also a massage scheduled for that room after theirs, so we had move that massage to a different room. This could have been prevented by simply asking each other if we had started the Riverbath or just going to look ourselves.
