I'm going to confront a guy who was using facetime in the locker room
Is there something specific about him using Facetime that upset you?
I don't allow anything to be filmed in the locker room
It is difficult to confront people sometimes but if somebody is doing something wrong like filming in a place where people are changing, that is not okay. It is normal to be upset and want them to stop
I am going to tell them to stop now.
I actually agree with you telling this person that his actions were wrong and inappropriate. I hope you are able to get this situation resolved and prevent it from happening again in the future.
