The 1942 Willys MB Army Jeep parked in front of The Thrift Shop on Chicken Alley in Vineyard Haven is authentic and used, but it’s not for sale. It’s the car that Noava Knight, the new shop assistant at the store, drives to work.

Five days a week, Ms. Knight, 26, hops out of the Jeep her boyfriend purchased on the Cape and strolls into the shop. She greets her colleagues, most of them more than 40 years her senior, and gets to work reorganizing, advertising and planning.

For many, Dolly Campbell is the Martha’s Vineyard Community Services Thrift Shop. Her bright red hair, positive welcome at the door and ability to assemble a team of enthusiastic volunteers is a large part of the charm of the store. But after 15 years of working as a comanager with Sandy Pratt, Mrs. Campbell is retiring.
