Yea the other day, I working here in BNA. I hop up the ladder after loading something like 86 bags in the back of our CRJ7... It was flight 4494 to ORD. SO, there mister FO, if you read this I am calling you out. I washed the windscreen as a courtesy. IT is not policy, and is NOT required of me to do so.
After doing this I wander off to get the lav service completed.
I get a call over the radio to go back and redo the windows the FO says I missed a spot. I go back redo and leave.... Again, this time I am hoooking up the tow bar and intercom. Go back and redo the windows. Got it, I climb back up the ladder and re wash them.
Once again as I am trying to drive the push to the plane, I need to rewash the windows.
Get my point?
You will never have your windows/lav/Pca ever hooked up again.
Moral of the story, be nice to your rampers.
