Well,
Gulfstreamaviator, since you agree that some rules have to be carefully decided due to local circumstances ... I guess it depends whether you (personally) are around to deal with the mess!
If, following your following of the instructions and turning off your electrics - you are no longer present - then it's someone else's problem, namely the CC!!
"Please could you turn that control box off?"
"No - you would not like the result."
"Regulations apply to everyone, equally."
"I don't think you understand..." 
"TURN IT OFF!"
"I did warn you." <click> 
CC to FC: "The cabin is insecure and, uummm, rather messy. Is there a contract cleaner on board?"
Hi
TS, welcome back to the real world, here inside PPRuNe! [OK, I admit it, there has been too much sunshine in the last week and my brain is fried.]
