i think the only time i ever 'performance' parented, and got thanks/praise for it was at a soft play.
DS is autistic and can be a bit rough.. he was running around with a group of other boys who were ALL being a bit rough, and being led on a bit, the others were being ignored by their parents.
The older kids aren't meant to be in the baby/toddler side of the thing and they were dodging in and out of there to the upset of some of the mums with little's in there.
I pointedly walked up to the edge and very loudly said "DS, you come out of there RIGHT NOW.. you ARE NOT allowed in there, and you're going to hurt someone, if you don't stop that, we will be going HOME."
I do it because to get ds to understand i have to be clear about what he's doing wrong, why he's doing it, and what will happen as a consequence.. its normal for us, i just did it.. kinda, louder/sterner than i usually would... treated it like when i worked in nursery/as a TA 
He removed himself, the other parents suddenly looked up and sheepishly called their own kids over.. a couple of the mums in the baby area said thank you to me.
I'm not in the habit of performance parenting, but i am certainly not above loudly parenting to make a point about other kids behaviour. (sorrynotsorry)
