I just returned from a business trip as well. During several meeting breaks, the conversation turned to food and how they couldn't wait to go the steakhouse of a well known celebrity chef after the meeting and have steak this, red meat that, etc. etc. etc.
Just playing devil's advocate here, but I wonder what the reaction would have been if I said "so full disclosure, I don’t eat meat, but I also won’t judge. I needed to just put that out there".
I can well imagine it would have created a divide between myself and the other people in the room...and to what purpose? Could also have been possibly viewed as coming from a "better than" attitude. Not saying that is the case at all, but it could have been viewed that way.
Now for full disclosure...I am actually an omnivore...I eat anything and everything, but just trying see the situation from a slightly different perspective. Trying to wear the other guy's shoes, so to speak.
