It's even less often you're excited to be there "with bells on" when the entire shift is unpaid.

However, Scrumptious assistant manager Dan Anderson will be doing exactly that on Anzac Day, as he and staff at three other cafes around Orange will open their doors to raise money for Orange Legacy.

Scrumptious, The Mills, Factory Espresso and The Burrow will all be donating every cent spent on coffee on Anzac Day to Legacy, which cares for some 300 dependants of ex-servicemen and women from Nyngan to Blayney, with most based in Orange or Molong.

Mr Anderson said it was a cause nearly everyone had a connection to.

"My dad was in the army, my dad was in the navy and it's about respect and showing we care for these people, we want to donate our time," he said.

"They gave up so much and giving up a couple of ours and donating our time is nothing compared to it, and all the money goes to Legacy so it's fantastic [from our perspective].

"I just think it's obviously such and important thing, it's a day to remember the people who have come before us and fought for our freedom and a lot of us have families, parents, grandparents who fought in different wars."

He said the amount donated each year was different each year, but headed towards $600 or $700 most years, however he said it's not so much the amount that matters as the community spirit.

"It's never really a competition but anywhere that is doing it, every cent helps, the customer who come and spend their money are just as important as we are for doing it," Mr Anderson said.

He also said it's the busiest shift of the year, but allows him to find that rhythm that will be familiar to anyone who's worked in hospitality.

"It is flat out, absolutely flat chat but it's so fun," he said.

"I think when it's that busy you've got such a rush and a positive mindset ... people are happy to wait, they know what we're doing it for and we all come together."

Orange Legacy's John Holman said he was pleased cafes had stepped up again for Anzac Day, with the average donations from the day $4000 for the charity.

"It's a very useful addition to our funds and it certainly helps promote Orange Legacy and keeps us before the public," he said.
