Let's not forget here that we are amongst people from all over the world, even if they sound like your next door neighbour sometimes. So something that seems completely normal for someone in country/state/city A may have you sound like an extraterrestrial being in country/state/city B.
So there might be 50% of movie theaters that will refund your ticket for any reason (I've heard some refund you if you don't like it, personally I find it preposterous, that's on you if you didn't make your research before seeing it, but hey, they're the one who decide.) and 50% who will laugh you out, you just happen to live near one or the other, doesn't make the couple in the story SS if everyone before them got a refund for a paper cut.
As for the biological waste, movie theater, grocery store, the bank.. it could have happenend anywhere. Pregnant women, even those that should have gone into labour 3 days ago shouldn't have to be restrained to their bed just on the oft chance that they break water in a public place. Stuff happens, nosebleed, throwing up from being sick, stuff from the other end, it happens, and for a broken water/labor, you have other things in mind than asking for a mop to spare the people it's the job of.
