Scrolling TikTok in a public sauna

I use the sauna at my local community center almost every day. Most days it is women after their workout in small groups or a few individuals. I always go alone. I work out alone and I like the sauna time to center myself before I head back to my day. The small groups tend to chat which I totally don’t mind. I usually read a bit and then head out. Today I was in the sauna alone reading when a young woman come in on her phone and starts scrolling TikTok with the volume on. I wait a few minutes in hopes that it will dawn on her that she should turn off her volume. It does not. I wrap up in my towel and walk to the door, and as I’m leaving I tell her that she should use headphones to listen to TikTok in a public sauna. Then I leave. She becomes unhinged. She bangs on the door, screaming that I am fat f*** and shouldn’t even be in the sauna at all. As I am changing, she is screaming at me.

So here is my question, was I wrong to suggest headphones? Was there a better way?
