Standards are slipping
I had to get quite cross with one of our CC recently when she tried to give me a cup of tea in the Blue cup. I am the Relief F/O I said, and therefore entitled to drink from the Green cup. The operating F/O may look a bit older but he's junior to me and not relief qualified so he must drink from the Blue cup.
Don't these people get it? It's not difficult, and clear logical SOP's are important in aviation!
