I have been asked to 'reproduce' a signature once in my entire life. At a 7/11, buying $6 worth of food. It took 4 tries to satisfy the cashier, because my signature is completely inconsistent. I almost refused, but I was curious whether I was even capable of signing convincingly.

To this day, I have no idea what drove that decision.

I try very hard to stabilize it to avoid getting franked at the voting site. (problem: Florida)
