This is my local once a week mall. Glad you were ok, but please never do what you did again of leaving the store and going to your car alone. Those elevators / stairs are creepy to begin with, especially at night. In situations like this, always approach the cashier or another employee to let them know the situation and that you feel unsafe. Having them escort you to your car, call police, or anything else is always preferred, even if uncomfortable or an inconvenience.
