Before you "bless and release" your customer, you can attempt to communicate with them in a way that will really help clear things up. It's called Non-Violent Communication or NVC. The Center for Nonviolent Communication explains that "NVC begins by assuming that we are all compassionate by nature and that violent strategies—whether verbal or physical—are learned behaviors taught and supported by the prevailing culture. NVC also assumes that we all share the same, basic human needs, and that each of our actions are a strategy to meet one or more of these needs."
NVC works based on these 4 principles of communication:
Observation - The facts of what you observe to be true.
Feeling - How do you feel about what you are observing
Need - Humans have basic human needs. What is important to you? Respect? On-time payment? etc..
Request - What do you request from your client (spouse, child, friend, etc..)
If you utilize NVC before releasing a client, you will know if the client can give you what you need, and vice-versa. There is a skill to practicing NVC, so try it out first on your team and at home. See what the results are. Then you'll have it in your back pocket for when the time is right.
