What a stupid bitch. lol
Something else to consider, babies spontaneously piss and shit. A point I like to mock my little brother about, how he had this tendency when having his diaper changed to blast everything with piss as it came off. Not to mention baby poo is runny as fuck sometimes, and if they fart as you're unwrapping it, that shit is going everywhere.
Don't be mad, fuckin baby facts!
This is isn't a breastfeeding issue or anything, there's no place for diaper changing in a food setting. That's fucking disgusting, I would've thrown her out too.
