Don't be rude
Don't be rude. Don't walk away if a person is still talking to you even if you already said goodbye. It is too disappointing to know that this person of known government position did it to a fellow female worker. The worst feeling is that I have known this man in position for years now and seeing him acting so unbecoming of a gentleman is so beyond words to explain.
Intimidation, threat and coercion will not earn you respect.
