Someone has to clean the fryer. Volunteering for the worst task says more than any interview answer.

Every workplace has a job everybody avoids and everybody notices. Taking it without being assigned says something no interview answer can, because words about work ethic are free and the fryer is not. It also puts you on good terms with whoever usually gets stuck with it, which matters more than the manager noticing.

Volunteer for the worst task once this week, quietly, without pointing it out afterwards. Do it properly rather than quickly. That is the reputation people describe to other people when you are not in the room.
