After 28-years behind the wheel of the SA Pathology car, volunteer courier Frank Dunn is finally handing back the keys.
Mr Dunn has spent every Monday morning for almost three decades dropping off specimens, supplies and reports to local doctors surgeries, nursing homes and other locations as required.
The 82-year-old retiree was first introduced to the role by a close friend and hasn't thought twice about volunteering since.
"The first two weeks I went with my mate and he showed me the ropes," Mr Dunn recalled.
"I thought, 'I'll be able to handle it from here'."
The volunteer service provides a valuable conduit between the SA Pathology lab and a range of health service providers in the region.
Starting off as a simple way to fill his time, Mr Dunn has mixed emotions about his last day on April 15.
"In a way I am sad to finish up, but I've got two hearing aids and I've picked up arthritis which is just another thing telling me it's time to give it up," he joked.
The former injector room fitter has a habit of sticking around. Before his time as a volunteer he worked on the railways for more than 35-years.
"The people make the job," Mr Dunn said.
"I've seen lots of people come and go as far as the work itself. You get to know the staff and the boss and after a while you get on a first name basis.
"It's been a good social thing, everyone sticks together and there is always a friendly face."
SA Pathology's Craig Wilsdon said Mr Dunn's infectious sense of humour will be missed around the office.
"Frank often sounds me out when he arrives at 10am on Monday for the start of his courier round to see how I am going. I'm sure he replicates this everywhere he goes," Mr Wilsdon said.
"He is also good at reminding us when the courier car is getting low on fuel with his subtle hints
"I know the local surgeries appreciate our Volunteers and Frank is no exception. Not only will we miss him, but so will they."
"His sense of humour will be missed and I'm certain the car will run out of Fuel now that Frank is leaving."
