Play the stupid game if it's only seasonal.
They're looking for reasons to whittle people off their list so you want to stay on the list as long as possible.
Pick something that not too cringingly reflects what that company actually does/sells, and have a look at their mission, vision and values on their website. Then talk about yourself in their terms, what their customers want.
EG if it's a bookseller, take your childhood copy of your favourite book and talk about how it influenced the person you then became.
If it's a garden centre, take a photo of an inspiring garden or your favourite flowers and talk about why you love them - the environment wildlife etc.
If it's a food retailer take something tasty to share like biscuits or chocolate and then talk about the pleasures of cooking, eating, family, culture.
They want someone who'll be a good fit, who will align with themselves what they do, and what their customers want ... so you might as well do it.
And if it's seasonal, they'll be looking for someone with energy and enthusiasm and an upbeat can-do approach, so play that.
