1) Find a store you like and go IN PERSON, don't call, for sure don't leave a message, and introduce the most charming version of yourself. If you aren't a hot or cute and demure chick and there is one remotely associated with your project, bring her, if she's an actor and a people person, coach her and have her ask. All the advice given here about -- say its a student production, no one is making any money, it's just a handheld digital, or its just a home video camera, is all good advice. also good advice to pony up $50 to the kid working there and as him to turn his head on the next scheduled day he's working. You might also try to do it after they close or something.
2) if its just a shot or two you may be able to fake it. take a digital still cam or your DVX in and take some quick background shots. Then put the scene together with green screen. Texas Fortune did this (in the Zombie Fest -- see link in my sig) and it worked well, but it only works for very limited short shots.
