The Allstar Weekend bassist had just delivered In-N-Out Burger to drummer Michael Martinez.
The fast food chain hasn't expanded farther east than Texas, but Quiseng, 21, recommends it to any York Countians who might venture West.
It helped the group power through rehearsals for their upcoming tour. They will perform tonight at the Maryland State Fair.
The band started in a San Diego garage when the members were in high school.
Quiseng said he remembers lead singer Zach Porter writing poems and trying to sing them.
"He's actually become quite the vocalist," Quiseng said.
Michael was the only member who was classically trained.
Quiseng picked up the bass for the first time during the first rehearsal. Nathan Darmody plays guitar for the group.
They recorded songs and made their own demos. Eventually, they won a competition and got managers and a record deal.
Quiseng said adjusting the band's new schedule of 12-hour days, interviews and appearances was daunting at first. But the band's growing fan base made all the hard work worth it.
New friendships were another plus.
Allstar Weekend was the first act to open for Selena Gomez. They all bonded and Quiseng said Gomez joked that she'd book them as her opening act if she ever landed a big tour.
When Gomez booked her summer tour with The Scene, she didn't forget her promise. Quiseng said the band was honored.
"It's going to be so much fun," Quiseng said about the tour. "The Scene are such talented musicians. It's like working with your friends."
The center of their worlds for the next weeks will be their tour buses, which Quiseng described as "a party house (on) wheels."
Aside from fast food, Allstar Weekend will bring along laptops for social networking and iPods. At the moment, Quiseng's was stocked with Dean Martin, Elvis and Frank Sinatra.
"Zach and I like to read," he said. "I'm going to finish ('The Perks of Being a Wall-flower') as soon as we hang up. I'm obsessed with it right now."
Other than that, the band's needs are minimal.
"We have each other," Quiseng said. "We have the experience to talk about every night."
But Allstar Weekend doesn't plan to be an opener forever. The group released its first album in October. Its sophomore CD "All The Way" hits stores Sept. 27.
Quiseng said their first effort was a collection of pop rock songs they wrote as teens. Their new sound is more mature. They experimented with hip-hop and R&B.
"It has a little swagger," he said. "We're getting older, we're getting better and we're growing up a little bit."
But for the rest of the summer, Allstar Weekend is going to bask in their first big billing.
Quiseng said that three years ago, he wouldn't have believed anyone who said he was going to be a rock star.
"When we were signing the paper it kind of hit me," he said. "I had never seen a (contract) before. (That) is what happens in movies. I lost my breath."
