I've considered it, but decided to choose anonymity over name tags. After all, unless someone uses your time machine to get the exact details again, I can always just quote Bill Clinton: "I did not have sexual relations with that woman".
Luckily nobody is secretly recording anything for, um, "security purposes". That's totally not a thing that anyone needs to be suspicious about. ¬.¬This image was decent enough to show the kids. Allow me to quote MehMeh: "wat een lief vosje"!
Decency is obviously overrated, but lieflijkheid never is. Dank je! 
Wait, what? Two holes!?
Alright, three, but the original holes are really just one long hole if you get technical about it.
