Authentication: Failed

For years I’ve been going to the bank to cash out some bucks the old school way and I didn’t have any problems. Today for the first time, I had it. I was denied of my access to my own money. 6 times I was asked to sign. All failed. Even with the authentication of my identification card against my finger print, the bank officer could not accept it. How strict banking system have changed. Obviously my signature shown in the screen was from since God knows when (liken unto a small kid’s signature; that’s how long it was), comparing to the current, I have to say my signature “evolved”. The only solution is to head off to the main branch and get a change of my signature. But heck I never knew how hard it was to do an initial beginning with “Z”.
