1) You conveniently and unilaterally changed the agreement in your favour.
2) You conveniently and unilaterally ignore the hierarchy / chain of commands in the organization.
By the way, this kind of tactics usually work well if the asking party is a female who does not have a d**k but have a pair of t**s. Of course it helps if your physical appearance is reasonably attractive. Needless to say, they can get away with many things time to time, especially from males.
I personally never envy those opportunistic females but I feel very sorry for them because one day their lives will be dramatically changed, especially, when a new leadership is brought into the organization – the new leadership does only deal with facts, not emotional garbage. That is the day when you will pay for the crime that you ignorantly committed.
