This is a topic I have been loooooonging to read about. Emotions, intelligence- that combo!
Hmmm, it really a topic every school should teach because I don't know how a classy lady, well dressed, porch and all would come off so sausy and rude to a waiter only because he is putting on a uniform and she, on a gucci dress. Like how?
Can't you be intelligent enough to see that the young man is still bittered about his current position as an ordinary waiter, and just hold back your guts. And even probably helping him with an extra tip.
You did a great job by analyzing what emotional intelligence is, most especially by defining it. It was worth my read.
As humans we really display characters that sometimes hurt the feelings of others especially when feeling you own everything which is not appropriate. Such people never think of tomorrow and this in one way or the other would really hunt them some day.
