WTF: I don't have any of this problem with public restrooms, but I get extremely uncomfortable walking into non-chain stores. Stores where the proprietor might take a personal interest in trying to sell me something.
I was recently in a wonderful book store in a rural town a few states away, with my mom. I liked a lot of what I was seeing, but I just couldn't focus. We were the only people in the store, and the proprietor was just... watching us (that's how I
felt, that is). It was one of the most awkward moments I've had in years. It had nothing to do with him.
Similarly, I dropped by a local festival last week, which had a booth about protecting a local stream. Right up my alley. I wandered around a little then quickly left. So... personal.
I'm used to having long hair *now*, but it may have originally been because I always found haircutting... distressingly intimate. Like a long physical exam, in public. I hated having it cut professionally, I tried to do it myself a couple times instead.
But yeah, I can pee just fine. Shit's irrational, I guess
Edit: My mom and I visited a different bookstore last month, where I technically knew the proprietor from many years ago. He obviously didn't remember me, which probably was pretty awkward as I insistently talked about the times we'd had a couple decades ago. Still, that tenuous one-sided connection was plenty to put me at ease, and I purchased a nice load of interesting books (:
