Being a cashier requires you to be independent most of the time, and interviewers want to hear that you enjoy working independently while still being a part of the overall team. Tell the interviewer that you like working independently and are resourceful using the tools you have been provided, such as cheat sheets, to help you find answers to any questions you usually have. Next, mention that you are also a team player and enjoy contributing to the success of the overall team and helping other co-workers by answering any questions they may have or helping them with additional training.
