How to measure human character

"Steve behaved very badly. He constantly talks down on the wait staff,"CT reported upon arriving back from Shanghai

I had to admit it, but there was a time in my early life that I, too, persistently leave others feeling demeaned and de-energised.

Now, as I know, the difference between how a person treats the powerless versus the powerful is as good a measure of human character. To me, when a person is persistently warm and civilised toward people who are of unknown or lower status, it means he/she is a decent human being.
