I remember one year they were short of attendants so asked me if I would help out, which I did. I was on duty on the balcony on the Sunday and two brothers were talking rather loudly so I told them to be quiet while the sessions were on. I had no idea who they were but they went off and I thought no more about it. Then during the lunch break an elder from my congregation who had asked me to be an attendant came to see me and told me I should have been more tactful when speaking to people, as a complaint had been made. Apparently the two brothers were the resident caretaker and a Bethel representative.
Not surprisingly they never asked me again!
