Ron is a mate of Bazza and AnotherBeanCounter, who 'earns a crust' by preparing drawings for Greenfield and Brownfield civil construction projects.  Probably learnt his trade back in the days of slide rules and set squares, but like nearly all of us now days has become an expert in dedicated drawing software which suit his needs, being ?? and ??. 

Hence, Ron, like most of us, spends too much time -

  1. staring at a piece of plastic facing him,

  2. talking into other pieces of plastic surrounding him; and

  3. tapping on other bits of plastic in front of him.
