Neat. I've been holding onto a domain thronehunter.com, for 10 years now, after a stint at a startup in a downtown metro, where the office was a very small "loft" with 10+ people squeezed in.
Myself and a few others fairly quickly had an aversion to using the lone bathroom in the loft for respectful reasons and instead began seeking out bathrooms at nearby hotels and elsewhere. We would often joke "hey I'm going to run to the Hilton, I'll be right back" or "has anyone checked if the Mariott is open?".
I bought the domain thinking it'd be fun to build a bathroom finder/rating app but never got around to it!
