Out of all of the flight directors, Glynn Lunney seems to do the most critical thinking when it comes to how to operate the LM and CSM, particularly in these conditions where they are forced to conserve as much power as possible. He's also not afraid to express his opinion, as indicated in this dialogue between himself, EECOM and TELMU. Still, what we consider "arguing" is probably just shop talk in their field of work.  :)

Edit: Listening back and forth through the tapes, it looks like this discussion is concerning powering the CSM's instrumentation from LM batteries. Glynn's preference is to use the CSM's batteries instead, but Burton has been adamant about not using them any further than he absolutely has to, so the plan is to use a LM battery to power it up instead. As a result of the possibility, however remote, that a catastrophic single-point failure - the deadfacing of the descent batteries - could occur as a result of the unorthodox configuration, Heselmeyer and Burton are working on a procedure where an ascent battery could be used instead. However, it's a complicated procedure, and it's taking a while.

Glynn Lunney, one for prudent timeliness - as he says later on, "for God's sake, let's not be 100% pure engineers here" - is getting impatient and wonders aloud if it's even worth all the hassle.
