"It's not the most fun thing when you get your car booted, and watching other people get booted, you know, people can be a little upset," he acknowledges.
Which is why Garfield is glad the public will get to see him and other Philadelphia Parking Authority employees at work on the A&E series Parking Wars, which debuts at 10 tonight.
"I think it's a really good idea that they wanted to do this, to show what our daily life is like, how we deal with the different problems, the different situations that go on during the day," says Garfield, 54, a friendly and funny man with a mustache and an affection for the cerebral punk band Bad Religion.
"I think it shows that we're human beings," he says. "We're just normal, regular people trying to do a job, and it's not such an easy job out there."
Parking Wars is the work of Hybrid Films, a New York-based production company that has given the TV audience a string of series that follow Americans to work. Among Hybrid's on-the-job shows: Dog the Bounty Hunter (find the bail skipper), Family Plots (bury the dead), and Take This Job . . . (clean up the crime scene, wrestle an alligator, coordinate organ recovery for transplant).
Parking Wars is "really aimed to allow the audience to walk in the shoes of the person doing the job," says Daniel Elias, cofounder of Hybrid Films.
"Everybody has a strong opinion about somebody who works in the world of parking," Elias says by phone from his home in New York.
The Parking Authority is especially fertile ground for a documentary because "it's a very emotional territory," says Elias, 40, a native of England who came to the United States 20 years ago to study film at New York University.
"In this country, people are very, very attached to their cars, and you've got this interesting chemistry between people who are performing a public service and people who are potentially losing something that is seen as a piece of the American dream . . . their car."
