WTF, TSA? Is it 3 oz or 3.4?

I flew last week, and getting through the metal detector, I then attempted to grab my carry-on bag, laptop computer bag, laptop computer itself (because it has to be scanned separately) and shoes from the conveyor belt. Not easy to do when you only have two arms. So I sort of got everything into my hands and then made my way to the bench where I could put my shoes back on and put the computer away. The process is broken.
