I think it is a guy. The person said they got a call from the headquarters of the gym they go to with someone complaining to them over the phone about something they put on social media about how this place allows babies in the adult lap pool and and that the people at the gym didn't like it. Most of the commenters believed it was actually someone from headquarters, but someone else said they think it was a Karen pretending to be someone else.
If it is someone who heads up all these gyms that is kinda creepy that they can harass a customer. Interesting story though
