As soon as the white pickup eases to a stop at the gas pump, Brian Gilbertson is out from behind the counter and into the frigid air, huddled into his denim Carhartt jacket. He rolls up the faded sleeves and gets to work.
Even when it is biting cold, Brian and his brother Darin Gilbertson are out in the elements, pumping gas or filling tires with air.
The kind of services they offer are reminiscent of long ago, when every gas station was full service.
Today, Bob's Oil in Grand Forks doesn't exactly fit in with the other businesses on Gateway Drive.
Along the modern four-lane road, Bob's twinkling "gas" sign sticks out like a classic car in a lot of Teslas.
Across the street from a Dairy Queen and two doors down from a Simonson Station Store, stepping into Bob's is like taking a step back in time.
Inside there are mementos from years past: old oil cans, vintage toy cars and an antiquated clock.
Brian and Darin have been coming into the store since they were 5 years old and younger.
The 53-year-old Darin remembers making a presentation in elementary school about what he wanted to be when he grew up-except he didn't actually know, so he just talked about what his dad did.
"I was just being lazy," Darin said with a chuckle, "but here I am."
The brothers say they work well together, but they couldn't be more different.
Darin, the youngest of four, is talkative and quick to laugh. He looks at everything from the bright side.
Brian, 57, is more reserved, but once he gets warmed up, he is just as open as his brother, if not more.
Darin mostly does the books and runs errands, while Brian helps customers with whatever they need outside.
Darin remembers Eddie's bakery that used to be next door to the gas station.
"Dad always wanted to me to go knock on the door, but I didn't want to because I was just a kid," Darin said. "But when I finally did, he opened the door and the smell of that bread baking, oh, it just made it worth it."
In the back room, paneled from floor to ceiling with dark wood, there is a desk piled high with papers and boxes. On the walls around it are old family photos and their dad Bob's Army memorabilia.
A photo of the whole family stands out from the rest.
Bob sits in the middle wearing a shirt that says, "What can I say? I'm Bob." While his wife, Yvonne, wears a shirt that says, "Bob's wife." His children and grandchildren wear shirts that say "Bob's son," or "Bob's granddaughter."
"It's just a family affair," Brian said. "If you weren't working, you were here cutting grass or hanging out."
Bob started at the store, back when it was Torreson's, as a regular employee. And when owner Ethel Stone died in 2007, she gave the business to Bob. Bob changed the name of the station from Torreson's to Bob's Oil in 2008.
Bob died in 2016, having worked at the station for more than 60 years, leaving it to Brian and Darin.
"For me, not a lot has changed since then," Brian said. "We've always just gone out and done whatever (customers) asked us to do."
Their clientele ranges from elderly women who have never pumped gas in their lives, to commercial truck drivers. Many have charge accounts that the brothers bill once a month, and some that they keep under the counter for when someone can't afford to pay this month.
Since Odin's Belmont Service, near downtown, closed at the end of August, the brothers said they have gotten some of those customers. Odin's was another full-service station in town.
Odin's is currently up for sale and the future of the full-service gas station is uncertain.
Owner Paul Helgeson has been battling cancer. He recently finished his first round of chemotherapy and is in better health, but has stayed firm on selling the shop. He wants to spend the time he's been given with his family.
"Going through that really puts things into a different perspective," Helgeson said.
He is in talks with three potential buyers, but isn't sure if any will keep the station full service.
"If I was physically able to do it, I'd be there," he said. "But I hope and pray that someone takes it over and runs it the way it was run for my customers' sake."
Brian and Darin said they don't think about the future of their shop too much, but they do think about the past.
Brian speaks of dedication when he thinks back on all his years at the gas station. And the two brothers do work hard from 6 a.m. to 7 p.m.
But that doesn't mean they don't have time for a little fun, too.
Years ago the brothers stuck a jack under a friend's car right outside the gas station. They raised the car less than an inch off the ground.
"So he couldn't tell," Brian said.
Then, they waited for their friend to leave.
"It had to be 15 or 20 minutes that he was pressing on the gas, revving his engine, not knowing why he wasn't moving," Darin said, nearly doubled over with laughter.
For a minute, when the two brothers are laughing together, they seemed like children. Both weathered by the harsh North Dakota winters, but still young at heart, running next door to get bread from the bakery for their dad.
