people who take care of figernails or toenails are called manicurists. Most of them are women, though there are a few men. As for the customers, they are mostly women, too. these days, american men buy more hair and skin products than in the past. but not many men want to spend money taking care of their figernails or toenails.
still, manicurists have plenty of work. Even when women are worried about their jobs or their bank accounts, they go to the manicurists. they may go out less to restaurants or to the movie. but to feel better about their lives, they continue to spend money on certain small pleasures--a bar of chocolate or a manicure.
