On first meeting a new Boss/Co worker etc : What you see is what you get !

I find the ' what you see is what you get' quote as arrogant. They're trying to intimidate you in a way of showing authority. This person isn't nice. And is probably trying to hide feelings of insecurity. I would find it hard to show respect to such a person. Definitely not management material.

I always feel that’s it’s coming from a selfish egotistical type. In other words, “I’m a pretty horrible person but I don’t care and have no intention of changing”. The sort of person who makes you want to run away as quickly as possible.

Quite frankly, if someone says that the first time I meet them, they won't be seeing me again!
There seems to be some people that think that supposedly old fashioned values, such as respecting other people's opinions, thinking before you open your mouth and just basically being kind no longer matter to anyone .
In my experience they will often say very spiteful, nasty things about anyone and I often wonder just what has made them so bitter and twisted - as I walk away from them, that is!

I've rarely had a boss who held true to "what you see is what you get". If only!

Defensive I'd say, for want of something to say because of their lack of experience in introductions and how to present themselves.

In my experience people who say WYSIWYG use it as an excuse to be rude.
