The QuikTrip Corporation, with some 750 locations in a dozen states, is advertising for full-time store clerks in the Tulsa area who double as armed security. In short, besides an ability to “provide quality customer service,” among the primary role of the $35 per hour job is to protect the location and those in it. The chain has reportedly trialed the concept in Wichita, Kansas and it has already seen success.
