Re: The guy's a nightmare.
You may laugh, but in a previous life, I worked in a Coca Cola factory, and at shift change one day there was a can of Pepsi in the "Team room" fridge.
There was an internal inquiry as to how it got there, but they never found out who did it... ;o)
IMHO the only good pop is a heavily diluted tonic water. (Diluted with copious amounts of Vera Lynn, obviously!)
