Slowly Olivia makes her way back through the store, keeping her arms across her chest trying to hide her exposure and ducking down behind shelves whenever she can, keeping an eye on the pimply boy at the counter.

The trip seems to take forever, but eventually she reaches the end of the ailse, the door to the back room right in front of her, just a couple of steps out in the open and she can make it through.
