Paraphrasing some of content:
The challenge is to be of service without becoming servile. We shouldn’t elevate any customer to the role of superior being, but treat each with human respect.
Human respect does not involve treating others as if they were superior or defining yourself through their expectations just because they're paying the bill. Human respect means being responsible, not overly responsible—a curious form of irresponsibility. Don’t cut others' meat for them.
Human respect demands that I respect myself so that I can respect others. Whenever I take that humbling step down and backwards, I can lose my own self-respect, and thereby forfeit my ability to really respect—or be of real service—to anyone else. When I can engage with my customer as a peer, we both seem more satisfied with the result.
