Customers were hit with a broom handle when a brawl erupted inside a nail salon in Brooklyn, New York.
The incident was sparked by a woman who complained about her eyebrow service.
Police say the fight started after the disgruntled customer hit a nail technician. At one point, she was seen being held as they waited for police.
The customer's grandmother was hit with a broom handle and sprayed with nail polish remover by a salon employee.
Two people - the customer and an employee - were arrested, police said.
Protesters now want the nail salon to be closed down.
