It's so easy
I think the reason we get so upset at astounding examples of bad customer service (at least that's what my email seems to demonstrate) is that most of us have given great customer service and realized that most of the time it's not only fairly easy, it's actually quite rewarding.
The Jesuits say, "what we give to the poor is what we take with us when we die." I wonder if the service we get in life is directly related to the service we give? (Thanks to Craig for the photo--yes, it was a personal call.)
