My marriage failed because I didn't treat my wife as well as I treated my customers

Customer service is for your spouse, too!

I take full responsibility for the shitty way I treated my wife, regardless of how she treated me. I definitely would have never reacted to my customers the way I yelled and screamed at my wife.

I was always much more careful in how I reacted toward my customers, but when I got home I didn’t have to be nice. And that was the problem, I never treated my wife with the same respectful consequence-oriented customer service that I showed my clients.

I would never would have been such an asshole to my customers. But I certainly was one toward my wife.

Good customer service = good relationship.

Crappy customer service = crappy relationship.
