The pensioner who received a free meal from a tradesman in McDonalds has thanked the kind stranger in a private video message and heartwarming note.

A Facebook video shows the moment Dave Love, 42, paid for 88-year-old Bert Bradley's meal as well as his own, before giving the pensioner $20 ‘for his next coffee’.

With help from his grandson, Bert has since sent Dave a heartfelt video message thanking him for his kindness.

Bert, a widower who has recently lost his daughter, is an extremely private man who does not want the footage shared publicly, but the video features the pensioner reading a thank you letter to Dave.

'I would like to thank David very much for his kindness shown to me in McDonald's , where I sit and have breakfast a few times a week,' he says. 'Thank you so much.'

Dave has since become an online sensation but he stresses that he simply did what anyone would do.

'When I looked at that man I saw my dad, who has passed away. I just had to help him,' Dave told Daily Mail Australia.

'Pensioners need our help. I just hope people who see the video remember to do a similar thing in the future.'

The video was secretly filmed by Melanie Langley, Dave's partner of seven months, who says he does kind things all the time.

'He has the best heart - he always puts himself last and would do anything for anyone,' Melanie, 39, said.

The couple met on Bumble and knew they were soulmates. Just months later they combined their two families and now share five kids.

Dave's eldest daughter Eliza said she was proud of her father.

'He does this stuff all the time, one day he was really broke but saw an old lady needed some money for food at the supermarket and gave her the rest of the money he had til payday,' the young girl said.

Dave, wearing his hi-vis work clothing, had offered to pay for Bert's meal alongside his own morning coffee.

As the pensioner put his change back in his pocket, the McDonald's server had jokingly said: 'That's gonna weigh you down now.'

In the video, Bert thanked Dave profusely before moving away from the counter with his order number.

But Dave then slipped a $20 note into his hand saying: 'That's for your next coffee.'

Dave says he doesn't want to be hailed a hero.

'It's not about me - it is about helping people out. I didn't do this for attention but I'm glad it has made people realise how far a little kindness can go,' he said.

Dave, 42, generously offered to pay for Bert's meal on Tuesday - and he quickly became an online sensation when a video of the kind deed went viral

And he is passionate about helping the elderly.

'These people built our country so we can live the lives we have today - for my generation and the generation after us,' he said.

'If I was prime minister tomorrow I would fix the pension.'

The tradie also made a comment about the other viral workman video from this week, where a man allegedly assaulted a stranger outside a pub.

'Not all tradies are bad people like the grub from Frankston who hit that bloke the other day,' he said.

Bert had initially resisted Dave's offer but eventually gratefully accepted the money saying 'thank you very much… you're a gentleman, thank you'.

Bert thanked Dave for his kindness, saying 'there's still some nice people here'

'There's still some nice people here,' Bert had said to Dave.

Bert has been given a year's supply of McDonald's.

The heart-warming video has been shared more than 20,000 times on social media and has received many comments from people praising Dave's kind actions.

'I'm helping the old fella out, he's down on his last 20 bucks,' Dave said to Melanie in the video.

'He's standing there with a whole heap of change… he's a pensioner and he's old, so I paid for his meal and I gave him 20 dollars. It is what it is, honey, it's life.'

Speaking to The Today Show, Dave said that he had been inundated with lovely messages from people all over the world.

'Every single one of them is special and I've read them all,' he said. 'It's just made me realise how many beautiful people there are in the world.'
