I am very social and extroverted, however, maybe because I have been a bully victim at school, I am easily sensitive to behaviors that reek of pushy and superior.
There are a number of situations where someone with a huge "stage" presence and air of superiority appears to talk down on you, laugh at you with a loud voice, try to sell to you something you know is wrong but they use body language to stop you from even answering. The majority of people with this attitude are in the sales and business development departments of our company and of our supplier companies.
Within my company, it's especially people who yell instead of talking, or laugh and say things without even giving me space to think of an answer. They say "Hey, set up a room for our meeting, I'm quite busy." and then walk away, without waiting for me, or forcing me to follow them.
How do I talk back to these people? How do I stand up to anyone who acts superior in business (even if they are not)?
Note none of these people are my formal superiors, but mostly lateral colleagues, seniors from other departments (especially sales and bizdev...) and external professionals trying to sell something or convince that their product didn't fail when indeed I had the evidence...
