I forgot what AFFES stood for = Army, Air Force Exchange System. Now I remember!
The BXs for the USAF, PXs for the Army/Marines and Navy Exchanges for the Navy/Coast Guards.
I used to be a Civil Service DOD GS-9 pencil pusher and a WG-10/E-6 Technical Sargent aircraft mechanic with the Air Force. Retirement benefits were great up to this day including all the COLAs over the years. I retired at the age of 49 in 1997 and have lived in the Philippines since 1998 to date, with just a few short vacations outside of the Philippines.
I'm known as a "Quadruple Dipper" Pensioner (all earned entitlements, no freebies) after 30 years of combined civil service and military duty!
