This reminds me of a situation that happened over a year ago with a pioneer sister at my congregation.
She was studying/indoctrinating a lady in the second school with the doors closed when the wife and I came into the hall at break time during Saturday service. We decided to hang out at the hall to see if someone was going out in the afternoon.
This pioneer sister suddenly ran out of the second school to go to her car, grabbed her head covering and then apologized because she didn't have it with her while indoctrinating a person in the Kingdom Hall in another friggin room where we couldn't hear anyways.
Totally crazy!!! Like I even cared in the first place!!!
