I had a similar problem once at my bank while submitting some inconsequential form but for bureaucratic reason the signature in the form had to match with what they had in the file. As I had opened account with them years back, I couldn’t recollect what I had signed then. The clerk at the desk helpfully turned her display for me to take a quick glance at the signature in the file which I copied in the form. Thanked her well.
