Hide and wait

You cut off to one side, ducking into an aisle cat-cornered from the doors, so Eddie won't be able to spot you immediately, tearing down it at full speed. The slaps of your bare soles hitting the concrete sound like gunshots in the cavernous store, though their echoes are muffled by the jam-packed shelves. Your breaths come short and raspy, and your heart thunders in your chest.

You cut to your right, sprinting a few more aisles down, before turning left into another aisle, choosing this one as your spot to hide. It's one of the hardware aisles, full of screws, bolts and other assorted fasteners. Partway down the aisle, you stop, grabbing onto a shelf just above your head, pulling for all you're worth as your toes scrabble for purchase on the shelf below. You accidentally kick several bins of hardware off the shelf, the various screws and bolts clattering and pinging as they scatter across the concrete. Within moments, you're fifteen feet up, squeezing yourself between the pallets and the uppermost shelf, willing your heart rate and breathing to slow down, hoping Eddie hadn't been close enough to hear the bins fall as you scrambled into the racks.

"I know you're in here, girlie! Come on out, and I won't hurt you!" Eddie's shout echoes through the spacious store. You lay there, snugged into the racking, ears straining for any other sounds he might make.

After a few moments, you hear the scrape of his shoes on the concrete, as he makes his way down an aisle near you, still calling for you to come out. You cast about you, looking for something you could use as a weapon, but find nothing but boxes of screws. Grabbing one, you find it's more than heavy enough to cause some serious damage, and you pull it close, as you hear Eddie turn down the aisle you're on.

"You can't hide forever! I've got food, water, and time to burn! You'll have to come out eventually!" The bastard's got a point. You're kind of thirsty, and you've got no supplies. If he decides to wait you out, he's got the upper hand. You've got as good an opportunity as any to get rid of him, if you can hit him with one of the boxes of screws, but if you miss, he's got a gun, and that trumps screws any day of the week. With the size of the place, there's no way he can watch it all. Maybe you should let him get a few aisles away, and make a break for it. All you need to do is squeeze through the racking and climb down the far side.
