It seems like either
a) We're only getting half the story.
b) There are clues that poor communication was the issue.
c) There is no story to begin with, just some perceived slight in the authors head.
One clue that poor communication might have been an issue, is that you and I are left here standing feeling like we are missing out on something in the story. That is not good storytelling, AKA it is poor communication.
Wu, more details! Maybe the "need to get a drink guy" was really ill and could barely stand up? For instance.
The way other people behave is often a reaction to how they perceive they're being treated. Perhaps the OP should introspect on how he appears to other?
In recent years I have started gathering feedback for myself from my peers, direct reports and managers. The issue I find is that only certain type of people are willing to be completely honest, for the rest it really depends on how much rapport you were able to build with them. I guess what I'm trying to say is that I try, but it's hard. :P
Author here. Sorry you (and many others) felt that way... I was trying to put together these moments without rambling on too much.
To offer my perspective on the things you mentioned:
a) I absolutely agree, there's always two sides of a coin. I can only describe how I felt at the time. b) Again, I agree, and communication is a two way art. Having said that, some of those moments I feel there were very little I could do in my end to turn them around. c) I did not claim those to be stories either, my intention was to share these things that have happened to me in the past and made me felt uneasy at the time, and perhaps make more people (including myself) to be more aware of their surroundings...
