Interesting. I was recently chatting with a brother who's the head of the Attendant Dept for his RC this year and he's only been about to recruit about 30% of the brothers needed; apparently many were telling him they were either unavailable or had already committed to working in Parking. So he called the Parking Dept Overseer and it turns out HE is way understaffed, with many telling him they'd already committed to working as Attendants!
At this point the Attendants Overseer is very discouraged and doesn't understand why the younger brothers (18 - 45) just refuse to step up and help. He and the Parking Overseer even escalated to the Convention Overseer and were told that the other conventions being held at the same venue on other weekends are facing the same issue.
All of this is rather amusing to me, as I know for a fact that in certain countries sisters are used as Attendants (yes, with badges), however it's just not allowed here (...yet...until NooLite of course).
