I know that you can't have visible tattoos or plugs. It says you cant have retainers in ANY body piercing, even those not visible to the eye (which seems odd to me but okay). How strictly do they enforce the "no plugs" rule? I have plugs in my ears, but I wear jewelry that makes them barely noticeable. My ears will never fully close so even if I take them out, I will still have a hole in my ear. Anyone have experience with this?
