If this was all going on, the place would have been chaotic. Surely whatever supervisor was around would have been called.
It probably was chaotic ... so chaotic that they told her to move her car (her screaming was probably putting a damper on business, doncha know ... :-) ...).
Can you imagine someone being in a medical emergency in their car, on the street and then being told by the police or paramedics to move their car before they treat her medically! ... LOL ...
From what I’ve seen everywhere I’ve ever come upon it in public, is that the patient is always left “in place” until paramedics arrive and then they determine how to move the patient.
