Hardhat etiquette is such a preoccupation for professionals in this sector that you will often see professional engineers wearing a dome hardhat with a tiny duckbill brim even whilst on nights out with friends when they are nowhere near their place of work.

They are also pre-occupied with ridiculously large sheets of paper and pointing at things which can lead to an RSI affliction known as engineers arm (not related to engineers wrist which is a common affliction among techies who can’t get a girlfriend).

Sadly they think they are cool whilst everyone else in the world thinks they are muppets.
