Stock “boys?” Very retro.
1961-1963 At night the boys stocked the shelves. There were no male cashiers back then.
I still remember Campbell soups being 3/53.
Shelf restorers?
When I started at UPS, I was a package car driver. When I retired 10 years ago, I was a service provider. Same job, different title that means nothing. A stallion at stud is a "service provider".
