We have a similar setup. Two rooms. Patient triaged with a strep test. Both rooms are occupied. The chart is forwarded to me, and the patient returns to the waiting room to watch The Incredibles. Room 1 leaves. Incredibles patient goes to Room 1. I walk in, strep is +, give penicillin, and the entire visit takes five minutes.
