John Mayer had to cancel his purchase when he represented his Amex Black Card without an ID, since he lost it. Usually, in cases like this we would hear the “Do you know who I am” line being thrown at the clerk’s face, but John just looked embarrassed.

Eventually clerk did recognize who he was and John was able to finalize his purchase, but he gets the entire 10 points for being a celebrity without ego. I haven’t seen that in a while.
