You're a Guest Service Attendant. You attend, obviously, to Guest Service needs. Cashiering, processing returns, managing defectives, backing up photo/cafe/sbux/carts, counting the day's money in cash office, filling out the paperwork to do advances to changefund and guest service, write and execute the break schedule for the front end, order supplies (varies from store-to-store who does ordering), and anything else that comes along.
For me, that also includes doing checklane POGs, managing candy/gum, and equipment maintenance.
