Okay, if you can't beat them...
My CPT a few years ago drank copious amounts of coffee at breakfast prior to a 3.5 hour flight home on the CJ. Nature spoke to his bladder and soon we were trying to figure out how he could de-fuel.
A large plastic empty drinks bottle was procured and discusssions followed as to how this could be engineered to fit Mr Wiggly into it whilst I averted my gaze. In the confines of the CJ cockpit it just couldn't be done.
So CPT does the walk of shame, past the pax who could bearly restrain their mirth and the curtain closed, etc etc. I think one of the Pax jnrs beat him to it and left his friend Richard behind.
