Graham O'Hare has been a milkman since he started working part-time at weekends when he was 14.
However, it wasn't until the Covid-19 pandemic struck that he realised just how much he and hundreds of his colleagues are appreciated by the nation.
The married father-of-four, from Kill, Co Kildare, has never been so busy.
While his orders for schools and workplaces have dried up during the pandemic, his phone is ringing off the hook for domestic orders of not only milk, but other essentials like juice, eggs and butter that have been stripped off supermarket shelves.
"A lot of people won't come to the door because they're terrified," he said of fears of contracting Covid-19.
Although he practises social distancing on his rounds, delivering to around 500 houses in Inchicore and Ballyfermot, he added: "I still have contact with them.
"I'm sure it does give a bit of brightness to people's days.
"People are coming up to me and thanking me for being out there. Complete strangers. It's nice to be appreciated."
He is among around 250 independent milkmen and women who are contracted with the online portal MyMilkman.ie, which allows customers to order and pay for home delivery online.
