I did make myself look bad and I did lose my cool. I accept the fact that that's were i went wrong and right now there's nothing I can do about it but learn to control my temper and respond better next time that happens.

But for me, In all honesty, I really tried to be as decent and diplomatic as possible. I couldn't just stand there while this guy makes a scene and makes fool of me at the same time. That's why i responded in such a manner.
