Friday, I was over in Gold Coast/River North (for you non-Chicagoans, that's the area directly north of downtown. It's REALLY ritzy and full of hipster-yuppies) and used a Starbucks bathroom. Yes, I still use the women's. When I came out of the stall, the two young yuppie-housewives jumped in shock and almost yelped! They exchanged a confused glance and gulped down their words. I was thrilled, I love confusing people...especially yuppies.
At work, there are unisex, single-stall bathrooms...that are also the family and handicap bathrooms. I really don't want to use those when someone with a sick kid or a wheelchair actually needs it more than I do. So I continue to use the women's; because it's O'Hare and, thus, full of weirdoes, I get odd looks only once a week or so.
It would still take a lot for me to use a men's multi-stall bathroom.
A lot of customers say "ma'am" and "lady" in reference to me. I like the respect (as opposed to saying "that bitch over there") and I shouldn't expect them to know to use gender-neutral terms like "rabbi," "doctor" and "captain"...especially since I'm not actually any of those social ranks. "Sir" and "bud" make me giggle, especially since the two people who have called me that didn't realize afterward that I'm neither of those. Maybe I should just make a new nametag for my uniform, "Officer K," and bug people to salute me.
