Hi Lima, I don't think you are old fashioned at all, in fact I think more on the "new fashioned" side. :)
Unfortunately we don't live in a black and white world where everyone always says exactly what they mean. Children hear all sorts of mixed messages all the time, that is just part of growing up to be a functioning adult. If they don't learn to make those distinctions as children, we eventually read about them in the news when they are the principal of a school expelling a child for pointing a finger at someone and saying "bang."
The fact is, children hear mixed messages and fake threats from loving parents all the time. "Go to bed or Santa won't come down the chimney" is one that many kids are probably hearing right about now.
Growing up I read a book called Struwwelpeter which was fully of cautionary tales of what happens to "bad" children should they not listen to their parents.

The Story of Little Suck-a-Thumb
"One day Mamma said "Conrad dear,
I must go out and leave you here.
But mind now, Conrad, what I say,
Don't suck your thumb while I'm away.
The great tall tailor always comes
To little boys who suck their thumbs;
And ere they dream what he's about,
He takes his great sharp scissors out,
And cuts their thumbs clean off—and then,
You know, they never grow again."
Mamma had scarcely turned her back,
The thumb was in, Alack! Alack!
The door flew open, in he ran,
The great, long, red-legged scissor-man.
Oh! children, see! the tailor's come
And caught out little Suck-a-Thumb.
Snip! Snap! Snip! the scissors go;
And Conrad cries out "Oh! Oh! Oh!"
Snip! Snap! Snip! They go so fast,
That both his thumbs are off at last.
Mamma comes home: there Conrad stands,
And looks quite sad, and shows his hands;
"Ah!" said Mamma, "I knew he'd come
To naughty little Suck-a-Thumb."
Somehow myself and over 100 million children in Germany, Austria and Switzerland were able to read such stories and distinguish that these were in fact stories and exaggerations. I knew nobody would sever my fingers if I sucked on them. I also knew God would not smite me into a pillar of salt if I took his name in vain. Children are smarter than we give them credit for. Learning to distinguish a bonafide threat from a fake one is IMO a critical part of growing up.
The point is, we have no idea what the repertoire is like in the household and cannot make a value judgement about "bad parenting" from one 30 second encounter. The lady was rude, no doubt about it... but lets not blow things out of proportion, we have much bigger fish to fry re: parenting.
