The Porter Shark

All Chat Pat about to order two additional sub-rounds.
His greatest fear in life is to be stuck in a round with slow drinkers. As he is a solution-orientated individual he usually has a couple of sub-rounds on the go, to enable the machine to stay well oiled. 
He is a real pro. 
Thankfully nobody from HR was present during today's work get together. Because the well-oiled machine is a constant liability past the 8th pint (usually 1.5 hours into the proceedings...)
