What do you think of people putting on makeup on the subway?

Actually, this is my story. Please tell me objectively. Please.

I was planning to meet a friend yesterday, but I overslept without realizing it. I hadn't put on any makeup, so I did it on the subway. I applied mascara and eyeliner. Then, an older woman asked, "Student, why are you doing your makeup here?" and told the person next to her, "Kids these days are such an eyesore." I was so flustered that I got off immediately at the next station.

I talked to my friends about it, and one said the makeup was fine, while another said it was rude behavior. I didn't even take off my mask, and I only applied eye makeup; is this really wrong?
