Returning Phone Calls

When a doctor's office is listed as "Accepting All Patients", but has a wait list that is so long that it is unclear that you will ever be able to see a doctor there and they promise to return a phone call in the morning but don't, you start to conclude that the clear English meaning of "Accepting All Patients" obviously means something else to people who have graduated from medical school.

Having wasted a day waiting for them to return the phone call as promised, we will now move on to other doctor's offices which are "Accepting All Patients" and see what version of English that they are using.
