Sex Appeal

Sally and Gareth had the perfect set-up going. They'd stake out the place they wanted to hit for a few moments, until they were fairly confident as to the sexual orientation of the clerk. Then, whichever way they swung, one of them would be outside and act sexy, before the other would hit the store and escape. There wasn't any good description of either of them, as the clerks would always be too obsessed with the 'unrelated' person outside.

This worked well until, after a scare with a bisexual clerk, they made the mistake of hitting an asexual one instead.
