I already sort of sperged about this but you don't know the half of it. I've given pedis to people half Amber's size and had shit like their toenails and skin sores come off in the bowl. I cannot imagine doing Amber's feet, especially with her huge overhanging calves. 3/4 of a pedicure is massaging the feet, ankles, and calves. Imagining the kind of filth and crust under her ankle roll is...
More on topic, if Amber doesn't have a dedicated foot doctor she's probably making Becky trim her toenails and give her those unprofessional pedicures she said she does. I'm honestly sorry for her in that regard. There's nothing like dealing with a pre/diabetic foot.
