Well ... not on purpose.Have/Would you ever use your CHL as a general purpose ID?
I can telecommute and work from home most Fridays. Sometimes during my lunch break, I'll go have lunch with my grandson at his kindergarten. Visitors are required to check-in at the office before meeting the kids in the school cafeteria. The receptionist usually takes my Driver's License and swipes it through a card reader and it prints a sticker with a picture ID for me to put on my shirt to wear while I'm on campus.
The time before last --> I went into the office like usual, handed her my license and she swiped. The card reader didn't work like it normally does, so she glanced at my ID and swiped it again. It still didn't work - so she compared my name on the kardex kept filed with the approved visitors list and read the ID again. She said, "Ma'am, don't you have a driver's license"?
So you figured it out -- I had handed her my CHL instead of my DL. Once I got the right card to her, I was swiped in without another hitch. She never acknowledged, if she recognized the difference in the first card I handed her... I just kind of laughed at myself.
I USUALLY keep the CHL in a separate section of my wallet to avoid that mistake; but I'd been to my FFL a few days before to pick up something or the other -- and after the fact, I realized I had put it back in the same section with my DL when I stuck it back in my wallet. I do try to pay more attention to that now!
