If its a FIS just humour them.
If they can't be arsed telling you about traffic if they are feeding there faces. So what if you miss the calls AS LONG AS you keep a fecking good look out.
I am may be getting bitter a twisted due to the local service in my Area (lossie) but they don't give you jack unless they want to move you in class G to make their life easier with IFR traffic.
So just follow the rule book and don't worry about it. BUT KEEP A BLOODY GOOD LOOK OUT.
