The man said he decided to fill up the gas tank while he was waiting, and he spotted another person at the pumps scratching off a lottery ticket.
He told his wife he was going inside to buy the same type ticket.
"I said 'No' at first," the wife recalled.
The husband insisted and went into the store to buy a $500,000 Jackpot scratch-off ticket, which he immediately discovered was a $500,000 top prize winner.
The couple said they plan to use some of their winnings to fund future road trips.
