It's not until I go to McDs for food when i have to endure a screaming baby and idk if the parents even tried to shut the kid up to realize, i really don't like kids.
I definitely wouldn't have the patience for one, and screaming and crying would drive me mad.
But seriously, if your child is screaming, either shut them up or leave. Don't make other customers and the workers suffer your screaming child.
I just hate people. There's not really much else to it.
