People taking personal calls at their desk.
People who witter on inanely about tea runs or their fucking holibobs especially early/late in the day when it’s clear you’re only there because you have a deadline to meet.

Reply all to some rubbish about running out of milk or similar.
People who don’t do their share or kitchen tidying, bin emptying etc.
People who ‘borrow’ your equipment but fail to return it.
