My first thought is have people check in at the front door and provide their phone number. Give folks 2 minutes to get to the store after you call them before moving on down the list. At least that way, someone could sit in the foodcourt or walk around. Other businesses that have had success with this approach? Try every restaurant who has a lot of volume. You know, you get that little pager whilst you wander around.
