Nice if you just stepped in some shit, just before opening a bottle.
I think I can understand your worry about that. Last time I was in Holland there was dog shit EVERYWHERE.
Luckily, American beaches, tiki bars, boardwalks and the decks of recreational fishing boats are pretty much fecal matter free, at least in my experience.
Although going along with your scenario, one wonders how drunk you'd need to be to look at the bottom of a shit encrusted sandal and either not notice, or think 'Yeah, why not?' I'm guessing that level of intoxication would preclude you from being able to stand upright and operate even a simple lever.
