Parents who adopt the loud, teacherish voice at places like zoos, museums, galleries etc also drive me mad. Brilliant that you're taking your kids to these places and that you're helping them learn: this is good. What's not good is that you want the 100 other people in the room, including the adults, to 'learn' from you as well and, ideally, be amazed at how clever you and your precious child are. "Oh LOOK, Hugo! These are paintings by VAN GOGH. Can you say 'Van Gogh'? He was from Holland. We went to Holland, didn't we? And we took you to lots of galleries and museums there because we are such excellent parents and at no point did we take you to soft play because that would be common. Now, WHAT FLOWERS ARE THESE? Yes, they're SUNFLOWERS, are they? Now, let's all sing the song you learnt about sunflowers at Middle-class Mummy & Toddler Club. I'm sure all these other people will join in and do all the actions because of course you do become distressed if everyone in the room doesn't do what you want, don't you darling? Oh, that lady is rolling her eyes at us? I expect she just doesn't understand because she doesn't have any children of her own."
Bah ha ha ha ha ha!
That made me giggle uncontrollably!
She's obviously been employed by the coffee shop to deter those guests who are just lingering to use the free wifi.
Crap. I was reading to my toddler in a cafe the other day while waiting for a friend, trying to keep him quiet and entertained. When she arrived he went into the high chair and the toy dinosaurs came out. I don't think I was speaking any louder than I would in a normal conversation. Is this what I looked like?
Have to agree @PoorYorick, NO you don't sound like the woman referred to in the OP. 
I think @Neutrogena is pulling our legs!
well I sincerely hope so!
And, as has been said, people are fine with children being around, if they are WELL BEHAVED, and not running around like feral animals, because the parents can't control them, or don't want to, because 'it's nice to see kids being kids!' 
Sorry but letting your child run ragged around Costa is just the height of twattishness for a multitude of reasons. (Including spoiling the enjoyment of other customers, and health and safety reasons.)
My local Costa has had to put a combination lock on its toilet/restroom because of badly behaved children, with 'entitled' parents letting them piss about in there, flooding the floor, scribbling on the walls with sharpies, and shoving tons of loo roll down the toilet! 
And no 'performance parenting' is NOT made up. Only people who are guilty of it are claiming that!!!
