I want to assume the expertise and competency of every person I interact with. Especially in the service industry. The best service I get is terse, direct, and professional
I don't understand why more people aren't like this. When I am interacting with someone who is at work, the trait I want to see the most is knowledgeable, not friendly.
If I'm dealing with you in a professional capacity it's because I have something I need from you. I'm looking for a result, not a conversation. And if my dumb ass is wrong about something then I want to be told why. That will force me to question my assumptions and possibly save me from mistakes in the future.
