I read an article about a similar WWII woman's service and more than anything these women's jobs were to be warm and friendly to a bunch of young scared solders who far from home and wondering if they'd make it back.

So they'd smile and they'd flirt and they'd charm and they'd dance and maybe the boys would feel less afraid or less homesick and maybe they'd have something to look forward to.

I'd bet just that was enough for some appreciative solders to give her a pin, if only to remember them by.
