An ambulance, parked in the middle of the road, sometimes obstructs the traffic. We apologise, but if there's nowhere else to park, there's nowhere else to park.
An ambulance, parked up, doors shut, but lights on, probably has some dedicated staff inside tending to a needy patient.
That dedicated staff, it may surprise you to know, is not only dedicated, but skilled.
And that patient, despite the indignity of being in an ambulance that may be obstructing the traffic, is still entitled to privacy.
On the outside of the ambulance, on each of the doors into the treatment area, there is a notice. "Please knock and wait. Patient treatment in progress". It's printed in large red letters.
When a doctor is seeing a patient, in their own surgery, the door is shut. For privacy reasons. People knock before they enter, and wait to be invited in.
So why, Doctor, did you feel it was your right to swing the doors of the ambulance open whilst we were treating the patient?
"I'm a doctor!", you sneered. No knock, and no wait. "Do you need my help?" you asked.
"I'm important!", is what we heard. "And can you please get out of my way?", you must have added.
"I don't remember inviting you in", was answered. "And you certainly didn't knock", was added.
We don't barge in on your patients when you're treating them. Don't you dare presume that you're allowed to do it to us.
Rudeness and oneupmanship will guarantee you one thing, doctor. And it most certainly isn't that we'll clear the road any quicker for you.
