As a customer service rep and supervisor in a call center for over ten years, I train agents to control the customers' conversation using guiding questions. These questions would help avoid any extra lengthy discussion and direct the customers on their purpose for the call. Many times I would get demanding customers.
There is one biblical verse that I have utilized to this day regarding my response to demanding customers, coworkers, and people in general. And that's Proverbs 15:1, the preacher says these words, "A gentle answer turns away wrath, but a harsh word stirs up anger."
In my experience, this verse works wonders. My manager once said, "The louder they get, the lower my voice goes."
In many instances, I've brought a resolution under challenging circumstances where customers had felt neglected and were on the precipice of anger. In taking heed to this one verse, I've de-escalated situations that could've led to physical altercations. I've also seen the flipside in what harsh words can produce.
The wisdom of God gives us correct responses to life situations that would ultimately reap good fruit. Taking heed allows us to align ourselves in obedience toward God's will in our lives.
