Your story has a happyish ending, I guess, but it's pretty disgusting that they banned you, without any recourse, based on false assumptions. "C'mon Miss," one of them said, "we know you're a stoner. We're going to fix you up." I actually wasn't a stoner and hadn't been for some number of years -- since I became pregnant and had a kid -- but I must have somehow created the impression that I was the kind of person who would be up for their smoky company. I think it was a compliment. It's interesting to find out that the person you are projecting is not the person you think you are projecting.Sometimes another's assumptions useful for your own self-realization.
I'd agree with that statement. We rarely know how others see us. Here's a time when I was misperceived: I was teaching in a community college. After class, I was walking towards the parking lot when two of the guys in the class came up next to me and each grabbed one of my arms and started leading me towards some bushes behind a portable classroom.
