But that’s what the Detroit Pistons call full service.

“Gas is on me today,” said a jovial Rasheed Wallace, stepping out of a red van at the Meijer gas station in Auburn Hills.

Joining Wallace at this media event to “pump up” fans for Wednesday’s regular season opener against Indiana were Chauncey Billups, Rip Hamilton, Tayshaun Prince, Antonio McDyess, Jason Maxiell, Kwame Brown, Walter Herrmann and Cheikh Samb, along with Hooper and Automotion dance team members.

From 5-6 p.m., anyone who rolled into the station received $20 in gas, pumped by the Pistons’ famous fingers. The players’ appearance was not announced until noon, but fans rushed out to Auburn Hills to be a part of the event, which was limited to the first 200 cars. “The first car was here before 2,” said Roger Lamont, store manager. “Between 4 and 5 we sold out.”

FOX 2, Channel 4 and WXYZ each came out to broadcast the spectacle, which got pretty congested as cameramen and cars weaved around each other. “It went very smoothly, everybody’s been a great participant,” Lamont said. “They’re all eager to see the Pistons’ team for this year.”

As it says on the Pistons’ customized bus, the players “work as one” - and aren’t afraid to give work to each other. “Yo, Rip. Ripper!” Prince hollered from two pumps over, motioning toward the car he was servicing. “We need an oil change over here.”

Hamilton, carrying his own squeegee from another pump, told her, “I’m the window guy,” and then diligently cleaned the woman’s windshield. “Whatever I do, I put my passion into it,” he said grinning.

No one could avoid the chill - except the drivers, who eagerly rolled down their windows to extend a shirt, hat or piece of paper for an autograph. Oh, and the Pistons, who manned their pumps for the full 60 minutes, filling up all 200 cars. Soon, any shelter looked enticing to them.

“How do you get under that tent?” Wallace inquired, looking longingly toward the radio tents of 106.7 The Fox and Pistons’ flagship station WDFN The Fan, which was broadcasting its popular afternoon drive show, “Stoney and Wojo.”

With the Pistons pumping $4,000 in free gas, the Meijer station in Auburn Hills made its money in other ways - coffee and gloves.
