A lot of people didn't know taking a selfie was an infraction, & what's the
big deal with it anyway? Does that staff member taking what is just another photo in 1000's taken of the average prospect really constitute some kind of competitive advantage???
It is a lot of nothing.
Now, if it is a photo in a strip club, casino, private jet, private yacht, resort or something, THEN it gets more interesting, but it was just a selfie in an otherwise compliant context. Nothing to see here, move on.
