Alzheimers- the other gray cell®

My desk- which doubles for work and home (and triples-plus, if you count blogging, editing, finances, etc.)- is never a picture of organization. When work calls come in, I tend to scribble phone numbers and other references on whatever the handiest free piece of paper comes into view. Sometimes, these get lost. This is one that didn't, other than pointing to something totally lost in my head.

It must've seemed a perfectly logical code at the time (abbreviations are as I wrote them down, except the last names have been removed other than the last one, if only to assist with solving the mystery):

Jamaal H
Brian S- mgr.
Nancy R
Robert Macbeth- a/u

And that's all he wrote. There's a punchlist of other crap on the bottom of the note, but those notes are upside down from those scribbles and I remember what the ʇɹɐd uʍop əpısdn meant.

I can't even think of what the last abbreviation might even mean, other than "alternate universe." Or, given the last name right before it, "approaching underbrush."

Anyone with a clue, please claim me at the Code Adam station. I'll be the one sucking my thumb and likely having forgotten who I am.
