Marcia, Peter, and Jan all get jobs at a local ice cream shop, each with varying results. Marcia's hired first, then Mr. Haskell wants to start taking afternoons off, so he puts Marcia in charge and hires Peter. Unfortunately, Peter starts goofing off; taking an ice cream break when he's supposed to be wiping down the rest of the counter, sweeping junk under one of the tables when he should have had a dustpan on the ready in the first place prompting Marcia to have to take over all the rest of the sweeping, making personal phone calls all afternoon and goofing off when he's supposed to be helping Marcia dust under the shelves. Finally, after three days of Peter goofing off, Marcia promptly stops what she's doing, marches straight on over towards him, turns off his radio while he was in the middle of listening to some sort of sporting event, and just simply fires him. Meanwhile, Marcia's boyfriend Jeff wants to spend more time with her, "business before pleasure" is all she can possibly tell him, because of her rather hectic schedule. Back at the ice cream shop, Marcia fills Mr. Haskell in on what happened about Peter, she also offers, on Mr. Haskell's behalf, about possibly having Jan hired as Peter's replacement, Mr. Haskell agrees, hires her, and she proves to be the complete opposite of Peter. At one point, just as Marcia's boyfriend Jeff comes into the ice cream shop with another young lady at his disposal only to get even with Marcia only because all he ever hears from Marcia is "business before pleasure" to his wanting to spend more time with Marcia, Marcia responds in seething humility by squirting Jeff and that other young lady with the whipped cream only to get even with Jeff as well, out of embarrassment Jeff and that other young lady promptly leave the ice cream shop. After a couple of days or so, Mr. Haskell realizes he's much happier running the shop than he is taking afternoons off, and decides to let Marcia go in favor of keeping the harder working Jan on the job. Although Marcia is at odds with Jan over being let go from the ice cream shop as Carol and Mike just barely manage to calm both of them down, Marcia's boyfriend Jeff calls, and after settling things between one another, Marcia realizes she has plenty of time for Jeff after all, and then Peter surprises everyone with a new job he got at a local pizza parlor.
