That's one of the main reasons that all the trademen who worked with me at one of the Ford plants had AVO books with them at all times.
When they were told to do something, they were more that happy to accomodate you...so long as you wrote it down on his pad (along with your name, date and time).
It ended the guys doing so many odd jobs while not getting their assigned work done, because we now knew who kept snagging them to do stuff that was not on the official to-do list.
Turns out that almost 100% of our problems were the Supervisors/Managers who thought these guys had nothing better to do than their tons of little jobs.
Once that was implimented and the guys knew that they wouldn't get in trouble so long as they could tell the boss what they had been spending all day on...and who told them to do it...that most of the timewasting sidetrack jobs stopped.
A great system, but a real shame that it was the only way to control the people who thought they knew everything.
