As an archery coach, GT, I have to ask people directly if they have any disabilities, long or short-term injuries, body piercings, etc that might have a bearing on how I coach them in archery. This is so that everyone is accommodated properly.
Body piercings are relevant. If you have pierced nipples, for instance, I'd strongly advise you to wear a chest guard when shooting.
Just saying because I think there clearly are cupircumstances when it is allright for a stranger to ask someone about disabilities or anything that might affect their ability to do whatever it is, or the coach's ability to teach them.
