For fingers, they let your fingers soak (if needed), shape the nails, trim the cuticle, buff them, clip evenly, paint la
For toes, they let you have a mini footsies hot tub with soap and oils and bubbles, while sitting in the most amazing massage chairs, then they scrub your legs and feet (until RAW... I hate that part), dry them, oil you up, smooth you out, trim the nails, cut and gouge your cuticles until it almost bleeds, buff your nails, paint, design, glitter, and let it dry in the UV.
they cut, file, and paint them, basically.
Pedicures and manicures.
