I can confirm that GB go out in field service. When I was there one of my friends drove some of the older members around out in service. On saturday mornings i'd see them heading in/out of the KH in 124 with mags and stuff.
as for Morris' wife in laundry, it was when she was in the service department so she wouldn't have been given that cushy job. even then depending on her age it could have been a 'part time job'
