Lucky Luke Pittard scooped a £1.3m fortune, but applied to get his old job back because he missed his workmates.
Luke, 25, and his girlfriend Emma Cox, 29, worked together at the branch of McDonald's when they hit the jackpot.
The couple hung up their uniforms and settled down to domestic bliss with three-year-old daughter Chloe in a £230,000 home, splashing out on an expensive wedding and a holiday to the Canaries.

Despite winning more than £1m on the lottery Luke Pittard decided to go back to work at McDonalds
But 18 months after his bonanza win the novelty of life without work has worn off and Luke has got his old job back as a staff trainer.
The lure of the kitchen proved too great for Luke who is up at the crack of dawn five days a week to clock on for his shift.
Luke said today: "They all think I'm a bit mad but I tell them there's more to life than money.
"I loved working at McDonalds before I became a millionaire and I'm really enjoying being back there again." Customers at the McDonald's in Pontprennau, Cardiff, have no idea they are being served by a millionaire.

Luke said: "There are so many familiar faces that it was like coming back to a group of old friends.
"Lots of my old McDonald's workmates came to our wedding and I had kept in touch with them all the time, so I just thought: 'Why not go back?'
"To be honest, there's only so much relaxing you can do. I'm only young and a bit of hard work never did anyone any harm."
The couple, of Pengam Green, Cardiff, earn more each week in interest on their £1,369,847 Lotto win than Luke brings home from McDonald's.
But Emma has backed her husband's decision to return to work cooking burgers.
She said: "I can totally understand it. We both really enjoyed working at McDonald's and still have good friends there.
"So it was really familiar for him and something for him to look forward to."
Luke's boss, manager Katherine Jones said: "Luke was always a great member of our team and when he won the lottery we were all so pleased for him.
"I'm glad he has had the time to enjoy his winnings but love having him here - it's as if he never went away."
"He was a good friend to everyone as well as a colleague and he's fitted back into the job so well."
The couple have delayed their honeymoon until Luke's soccer team finishes its fixtures at the end of the season.
Luke plays in goal for his local team and would rather dive headfirst into a muddy goalmouth than laze around on a sun-kissed Caribbean beach.
He added: "I must be the luckiest man alive - not only did I win a fortune but my wife understands the importance of football and now I've got my old job back."
