It's a million-dollar question: Does money buy you happiness?

In the case of five female co-workers at the Snack Shack diner in Kentville, N.S., who split lottery winnings two years ago, the answer is yes … and no.

Stephanie Dunham, Joanne Gillis, Valerie Archer and two other women who made up the "Snack Shack Girls" made national headlines when they won the Atlantic Lottery Jackpot worth more than $15 million in June 2013.

Not much has changed for Dunham since that fateful day, which was also her 49th birthday, besides the amount of zeros in her bank account.

After a brief hiatus, she's back at the Snack Shack but with a key difference – she's now the owner.

The restaurant had closed down, so she purchased it as a gift to herself and to her community.

"I just had to have this place back open, it's been a landmark here since, I think, (1934)," Dunham told CTV Atlantic. "It (was) kind of a shame to have it close down."

The diner's grand re-opening on Monday had help from a familiar face.

Former co-worker Joanne Gillis jumped at a chance to take on the breakfast shift again, although everyone knows that she's under no pressure to work.

And they aren't the only two in the group that still keep in close contact. Gillis says the Snack Shack Girls meet once a month.

And while Gillis and Dunham have settled into life as millionaires by keeping to their old habits, Archer struggled to adjust.

"I called the lottery company probably two weeks after we got the cheque," said Archer. "I said: 'Can I give it back?'"

Archer admits she has dealt with anxiety after cashing in her $3.4-million portion. Entirely unpretentious, she stills lives in the same small house where she grew up, although she has done some major renovations.

Archer's only other indulgence was a new car, which is now two years old.

She says it has also been difficult dealing with the surge in popularity.

"You got friends coming out of the woodwork who you haven't talked to in years, and it's like 'Oh, OK, you remembered who I was," said Archer.

And while the Snack Shack Girls is now more of a millionaires' club than group of co-workers, Dunham says it is still taking some getting used to.

"You have no idea how much money it is, even when you see (it) in your bank account," said Dunham.

"I can say the number and say 'Yeah, that's a lot of money,' but to picture how much that would be, (I have) no idea."
