I was told one time at work that I was intimidating; a long time ago and a different job. I was absolutely floored. I'm not that big a guy, and I'm always nice to people, sometimes too nice.
Then come to find out that the woman who accused me of being intimidating had some serious drug and emotional issues.
The owner just shrugged and let it go. I left about a year later for much different reasons
