Just as the people in front of Dr. A were walking through the entrance door, the store manager, having given his warning to the shoppers inside that it was time to close, noted that it was in fact now time to close and hit the switch that locked the entrance doors just fractions of a second before Dr. A stepped on them.
In my experience, the doors are turned off by a switch at the top of the door by a manager who is standing right there and who then locks the doors manually. It seems unlikely that they would be closed in somebody's face with no explanation.
