Random thought #2: most typed notes these days are sprinkled with widely-understood shorthand notations, e.g. LOL, ROFL, IMO, WTF, ...
Breed the two thoughts, and you get ...
A dictionary of help desk shorthand
ACE - Another customer error
AFTUNG - Application failed through unexplained network glitch
APADNSAC - Application performing as designed, not sure about customer
BRAZIL - Customer is nuts
INABIAF - It's not a bug, it's a feature
NIT - Network is toast
PIIS - Plug it in, stupid!
RTFM - Read the freakin' manual
SHAFAWISM - Server had a fit and went into single-user mode
SINP - Software is not psychic
UCOW - User can't operate Windows
Important note: all the above are entirely fictitious. Almost. Whatever! We would never, ever ... ever ... put anything disparaging about a customer into a help desk ticket.
