It's a false dichotomy - the solution to being able to handle emergencies quickly is the same as the solution to being able to see patients on time - have some slack in your schedule. Of course, that may mean that you need to charge more for your service, but I know plenty of people that would happily pay a surcharge of 20% or so on their doctor/dentist visits if it meant that they wouldn't have to be sitting around in a waiting room for an hour.

The curious thing about it is that it would only need to be about 20% to get everyone clear, but instead of that, nearly every patient ends up needing to wait for an hour, because there is always an emergency that needs addressing each day. I wonder why we don't see doctor's surgeries or dentists doing this. Anyone have an idea?
