ELANORA tuckshop convenor Renee Lipinski gave swift justification for Education Queensland's inaugural Tuckshop Day.
"Kids love seeing their parents working in the tuckshop," Mrs Lipinski said.
"And it's great for parents to see their kids in the school environment."
She was one of thousands of convenors and volunteers who Education Minister Cameron Dick said was and will be recognised annually on the first Friday in November.
"More than 20,000 people volunteer their time on a regular basis to provide this vital service to Queensland school students and staff," Mr Dick said.
"In both state and non-state schools, volunteers and convenors work tirelessly to make a significant contribution through the service and extra resources they provide."
Mrs Lipinski works with fellow convenors Liz Ellerby and Kathy Collins, volunteer Louise Reed and others at Elanora State Primary School's busy eatery.
She said volunteers were "fantastic" and allowed convenors to focus on management.
"We always welcome grandparents, mums and dads to help out.
"It's nice to be recognised, and a lot of people don't realise it's a job.
"It's fun, great working with the kids and it's very busy - we report to the P&C and profits remain in the school."
Deputy principal Pip Traucnieks wore her "I love tuckshops" badge last Friday and said without volunteers and convenors tuckshops would not open.
"It would be a blow to the parents who rely on it daily," Ms Traucnieks said.
"Plus we'd have a lot of kids going without food, and we can't have that."
