I'm all for using the "old lady" to your advantage. My grandmothers used to do it with "Just pop upstairs and get me.... Your legs are younger than mine." or "Run to the corner and post this, you're quicker than me."
I'm doing the "I'm an old lady, can't do that" routine.
My GCs know it's a bit of a joke. They do sometimes ask me "What was it like in the stone age?" and I have a range of replies one being "Quieter, children knew how to behave>"
I'm sure your GD didn't mean to hurt you.

Not really a scam or fraud, but I wasn't sure where else to put it.
