My son, who is a trainer at a large fitness chain, ran into some trouble when a member spotted a pic of him on social media wearing his mask, but NO GOGGLES!! <shudder> The club's requirement is that all trainers must wear both mask & goggles; not exactly sure how goggles will help anyone as my son already had COVID in November.
He discussed it with his supervisor, and the boss agreed that he could keep his goggles on his head during training, but to make sure he had them on for any group pics on the gym's web page.
