Three men who drove over 80km from Co Meath to "buy burgers" in Ringsend were some of the dozens of people fined for going outside their 5km zone this week.
They were stopped at a checkpoint at the Sean Moore Road in Dublin 4 in recent days, and told gardaí they were on their way to buy fast food.
Officers there told them that wasn't a good enough excuse to stray so far from home -- and fined all of them 100 euro each.
In all, 37 people have been hit with fixed-charge notices for going outside their local areas without good cause since Friday.
In Midleton, Co Cork, a woman was fined after being found at a beach outside her 5km limit, having already been told to turn around and go home.
Two cyclists were stopped in Carrick, near Galway, after their spin took them 19km from home and into the next county.
And in North County Dublin, four people were caught coming out the back entrance of a gym.
They were fined, along with two gym instructors inside who claimed they had to be there to teach online classes because their home internet was broken.
Deputy Garda Commissioner John Twomey says with the health system under serious pressure and a rising death toll, the force would be taking a firm line in its enforcement of the Public Health Act.
Meanwhile over the weekend, officers in Wicklow handed out over 50 fines over illegal parking at beauty spots.
The force says "significant" checkpoints and patrols will be covering the country this weekend to continue enforcement the pandemic restrictions.
