Back in my day (which wasn't terribly long ago) whenever there was an oral of some sort and you didn't know the answer, the correct response was something like "I'm not quite sure of the answer, but I know where to look it up to find out"

Not to bash on you specifically, but many people come here to the forums looking for basic info. It drives me nuts. Try looking it up first.
Scheduling, payroll, etc,they all benefit when people don't know the rules by which they are working.
