restricted sample set

When you only encounter someone in a work environment it's entirely possible that you're only seeing a special persona they only assume when in work, and that many of the unpleasant qualities of that persona are deliberately simulated in order to ease the passage of the persona's owner through the workplace and their career. They might have met someone particularly unpleasant but unfortunately successful early on in their working life and copied what they felt were the aspects of that person's character which contributed to the success, with the side effect of contributing to their unpleasance.

It could be that some people who appear unplesant are simply unpleasant, and possibly just emphasise this at work either deliberately or unconsciously.

As well as my workplace sanitary-behaviour guide Basic Toilet Hygiene for the Gentleman Employee and management staff-handling handbook Understanding Employee Single-Instance Disorder from your Employee's Points Of Views I shall have to find time to write something on game theory as it applies to the workplace, where alongside the usual "hawk" and "dove" strategies and their interaction characteristics and uses there will be strategies known as "slug", "harpy", "skunk" and "sandpaper-covered cactus".
