OK WP, I don't think anyone on here won't accept that some people have genuine legitimate reasons for not being able to wear a mask and I don't doubt that the runner you know is one of them. What seems off to me is still that on the facts presented the communication with the RO still seems intended to provoke a reaction. It's just a shame they didn't take a more cooperative approach in which case the RO might very well have welcomed them to their race.
