This bloke unfortunately learned the hard way that no good deed goes unpunished.
Anyon Rettinger ended up losing £4,000 ($5,000) after falling for an Apple Pay scam while trying to be a Good Samaritan.
And the 27-year-old has warned others to be wary when considering helping a stranger.
The lad, from Milwaukee, Wisconsin, explained that he had been approached by a young boy while he was working on his car on his driveway last month.
The agitated youngster - who Anyon said was no older than 12-years-old - asked him to use his phone, explaining that he needed to contact his parents.
According to Anyon, the child had rode up to him on a Lime Electric Scooter - which are dotted around towns for people to pick up and pay for a ride.
He explained to WISN: "He just starts asking me if he can use my phone to contact a parent.
"He was scootering and his funds were running out and he'd went too far."
The kindhearted bloke then obviously let the distressed kid use his phone, unlocked it and 'turned away for just less than a minute'.
He got his phone back, the boy trotted off and that was that.
But Anyon soon realised the youngster hadn't actually dialled his parents in a panic - he'd opened up his Apple Pay instead.
He had managed to transfer a whopping £4,000 into another account without Anyon realising.
He told WISN 12 News: "That internal panic kicks in, you know?"
He desperately tried to get the transaction cancelled, but was told that it was deemed a 'valid charge'.
The bloke was even charged an overdraft fee.
"Even my recurring bills are not remotely as high as thousands of dollars," Anyon said.
"So this should have had a red flag on that through their system.
"In a very large grand scheme, it isn't that big of a deal.
"But for a 27-year-old that doesn't have a lot of money that's trying to make it? It's huge."
According to CBS, Anyon eventually managed to get his cash back after a lengthy and difficult battle with the bank, as well as filing a theft report.
It turns out he is not the only victim of the scam either - as several locals have also fallen for it.
State Representative Evan Goyke also said that around 15 people have contacted him saying that they've had a similar encounter.
Police in Milwaukee are now investigating the virtual pickpocket, while Apple was also said to be looking into the scam.
