And another twist? Both of their kids have worked for Kmart over the years as well!
The pair - who live in Ferntree Gully in Victoria - said much has changed in the store over the years, with Catherine revealing they once sold birds and fish!
She also said she once used to have to work in Kmart’s chicken bar, cooking chooks on a spit for customers.
Speaking to the Herald Sun, Duane adds: We sold guns and ammunition in the sporting goods department.
‘That would have been in the late ‘70s.’
Duane finished up at the store last year after 26 years of service, while Catherine is still with Kmart after 32 years. She adds: ‘The staff are special people,’ Catherine said. ‘I think that’s why I stay.’
