Don't want to wait? Try to snag the first or second appointment of the day. "Earlier appointments in the day generally have a shorter wait because if the doctor gets backed up and is a few minutes late with each patient, a few minutes late with your second patient is going to be a lot less than a few minutes late with the twentieth," explains G. Caleb Alexander, M.D., assistant professor at the University of Chicago Department of Medicine. Willing to wait but want more face time? Steal the last slot of the day. "I save this for patients that I think are going to need extra care," he says. "Since no one is behind them in line, I can spend more time with them."
