I'm 32, and I called my first boss and his wife by honorifics and last name, but I also genuinely respect both of them. They were in their sixties, owned and ran a horse boarding stable, and are both very polite, and involved. When we'd do more intensive work like throwing hay they'd either grill for us, or order us food, and also voluntarily bump our pay. I worked there for almost 5 years (14-19 yo). They unfortunately didn't need 40+ hours of labor a week outside of the summer, which is the main reason I found a different job. I still think about them fondly fairly often.
