NAOMI Geddes sees an average of 300 cups of coffee sold every weekday at Rockhampton's Blue Truffle Gourmet Deli.
But today each cup will make a difference, with $1 from every sale donated to a local charity as part of CafeSmart.
The event is held in cafes across Australia to support charities helping people who are homeless.
Last year 275 cafes raised almost $83,000.
In Rockhampton, the $300 raised by Blue Truffle was donated to the city's Women's Shelter.
Although the charity is yet to be decided, Blue Truffle have teamed up with the Chat Room Cafe to run the event today.
Blue Truffle manager Naomi Geddes said the partnership worked well as both businesses were looking to give back to the community.
She said there was no better way than through coffee, which was one of the cafe's biggest sellers.
"People don't even think twice about buying a coffee," Naomi said.
"Last year went so well.
"It's putting back into the community and going back into Rockhampton charities."
