Maybe while she is teaching the students she finds bragging about what she makes gives them incentive to stay in the class and refer friends to the class and since the students are enamored in how much they can have when they become nail techs she thinks her clients will be enamored by it too? I think I would try telling her so since your so rich does that mean you don't need a tip. lol I know of an awesome bakery that makes a 3 layer 10 inch round for $23 that is the most amazing cake I have ever eaten. Maybe try different bakeries or find one others love and save some money.
