Ignoring the arsey tone of your reply, maybe I didn't make myself clear.
Do me a favour mate and stick to what has been written rather than making up a comment like that to suit the argument you are trying to make.
Depending on what duty you are finishing and where you are finishing you do not always have 30 minutes of duty time to make this call - if you are positioning you may go off duty on arrival at the gate. The next thing I'll be asked to do is call in on a day off - again people who do not know the detail (like yourself) are posting complete uninformed rubbish in this forum. - now, was that arsey enough for you
