Imagine this. Yu schedule a doctor's appointment. You show up on time after taking a whole day off work to get a wellness exam. You feel fine but you would like to know if you are hypertensive like your mother or diabetic like your older brother. What you did not bargain for is the 2 hour wait to be seen. You decide to cancel your visit because you have to pick up your kid from school. What's unfortunate is that after you cancel you do not reschedue because you just don't have the time.
