It looks like the captain had a vendetta against this chap, maybe he stole his chicK the previous night.
I do get vexed when I read the holier than thou reports.
There would not be a pilot in the world (except those that do not take alchohol at all for any reason) that has not been on a bender of some sorts and then had to go to work.
I have done it and had a real hard day, and when I was a captain, I had the odd co pilot who had been on the booze up to the legal 12 hour bottle to throttle rule and still reeked of booze.
My responce was dependant on the route to be flown etc,but it was usually TFN on this leg.
We will have a parley about this at the end of the day.
At this point I become very biblical.
HE WITHOUT SIN, CAST THE FIRST STONE.
