Not much in WDW grosses me out - or in life in general.
The bare feet in bathrooms thing is somthing I don't like to do (or in the gym locker room either for that matter - Bally's = Microbology experiment gone awry - really, athletes foot happens), but thats MY thing, and if it comes down to it, I have gone barefooted in locker rooms and bathrooms. But as for other people doing it, if you want to strip naked and roll around in the public bathroom, thats not going to gross me out. I may not want to be your friend (or maybe I do, this whole non-romantic thing in WDW has me thinking - divorced guy finds naked WDW fan rolling around on public bathroom floor - makes a good "how I met your mother" story if nothing else)
Anyway, not much grosses me out. Many things get me "miffed" but, hey, it's WDW and its not skin off my nose, so things like people texting, and 6" heels, and unattractive clothes, and palmetto bugs are all part of the game. Live and let live.
Hmmmm. Naked woman in 6 inch heels rolling around on the bathroom floor while eating a turkey leg and drinking Beverly. Call Imagineering, I have a new attraction to replace the clubs in PI. Dave's naked bathroom and turkey leg roll around
