I am a woman at least 18 years of age or older. I understand that if I am under 18 or not a woman, I will not be able to participate and I will not be given a refund.
I am an adult female and can provide ID to prove that I am over the age of 17. I agree that if I am not at least 18 or older or not a woman, I will be turned away and I will not be given a refund.
Okay, those are both pretty sloppy. Can anyone help me make the wording more clear and professional? Thanks!
