Planet Fitness is a franchisor with 2.5k gyms in North America. A woman entered her local gym in Alaska to find a man standing in front of the mirror shaving. A 12 year old girl in a towel was sitting in the corner. The woman confronted the man who said he was LGBTQ and could be there. She asked him to leave and he refused. She took his photo (he was fully dressed with shirt hair and looks exactly like any other bloke) and complained to the front desk, who did nothing. She has now had her membership canceled and she has been reported for taking a photo of a member which is against the rules.
She said she is going to report his presence to police.
