I use my credit card along with my driver's license to make purchases.  I recently was making a purchase at a furniture store.  I handed the clerk my credit card, that says "see id" on the back of it, along with my drivers license.  She slowly walked away to the credit machine looking back and forth between my license and me.  She ran the card through, but upon returning to the counter where I was waiting, she leaned over and gently said "Have you lost a lot of weight in your face?  You don't look like your license photo." 
I realized she probably thought I was a cancer patient or some other wasting disease because she was trying to be quiet about it.  Of course I had to bust out a chuckle and tell her that yes I had indeed lost a lot of weight in my face, and all over, from recent WLS.
She was instantly both relieved and curious.  After the usual questions, she told me that I really should look into getting a new license photo.  She could have refused to take the ID since it doesn't look like me in the photo.  It had been a while since I had looked at my license photo, and indeed, it doesn't look like me.
My license isn't up for renewal until next May.  Anyone else updated their picture before needing it for boarding a plane other ID related stuff?
