KLC doesn’t announce “no photos of staff and other passengers”.
KL does, but not always. On one KL flight this week the announcement included the instruction not to shake hands. I honestly can't remember when I last saw people shaking hands on an airplane, but I'm nevertheless convinced that this prohibition will save countless lives. Probably even more than the announcement I had to listen to umpteen times at CPH, which exhorted all and sundry to "refuse kisses on the cheek".
