““Anyone” can scribble “anything” in that little box.
It is not like a signature ever gets matched up anywhere.
I have just done a scribble, or a dash, or wrote “Elvis” and
it does not matter, it all gets accepted and goes through.”
True... I can see it now...
“Let me see the signature on file... Look... Do I look like Elvis to you?”
Lol
Correct.
You seem to understand.
“Signature Required” is a meaningless exercise.
