Why do so many people think WTD break = 30 mins per 6 hours?

lolipop:
Forget WTD break times or any other rest break, for me anybody who only has 15 in 6 wants their head looking at, 15 is barely time for a toilet break at MSA never mind having a cuppa as well. No medals given out for being over keen to impress the Boss.

Nobody in our office waits until their break to go to toilet, therefore I dont put it on break when I go to toilet. (Unless it suits me of course). Point of principle in my opinion.
