Richard Carr, 29, had picked up the Merry Millionaire card while he was waiting to travel to work.
He was so gobsmacked by his win that he 'acted like a lunatic' and continued to work – with the winning ticket tucked in the pocket of his uniform.
Richard said he would now quit his job - and is looking to buy a house closer to family.
Speaking at The Campanile Hotel in Doncaster, South Yorkshire, where he works the dad-of-one said: "I absolutely love working here but this is a once-in-a-lifetime opportunity and I'm very lucky to now being able to step back from work for a while.
"Most of my family live down South so I'd like to look at buying a house closer to them.
"Having lived in a hotel for many years, it will be amazing to have my own front door. And to have mortgage free house under 30 is unheard of.
"I lived in the hotel to save money but now to have my own space, and somewhere my son can help me decorate, is a dream come true."
On his winning day, Richard said he had just dropped his seven-year-old son home and decided to treat himself to a scratchcard to kill some time.
He said: "I walked out of the shop and started scratching the second game panel when I glanced down and saw that the symbols matched and they were worth £1 million.
"I ran back inside and thrust the card at the girl behind the counter - I think she thought I'd lost my mind as I could barely speak and must have looked like a madman.
Despite his amazing news, Richard managed to get himself together to get on the bus, albeit in a daze, when he was due to work the evening shift.
He then worked his shift with the winning scratchcard tucked in a pocket of his uniform.
He said: "I kept checking it was there every five seconds, it's not every day you have a piece of paper on you that's worth a million pounds."
Richard is now looking towards the future, and his son.
He said: "This won't just change my life - it will change my son's too. He's only seven so is too young to understand at the moment, but he knows that something exciting has happened.
"To be in a position where I can set money aside for him, for his education, for university or a car or a house is the best feeling in the world. He will have so many opportunities."
