Good idea to do this stuff at that age as you just get taken home to momma if you get caught. If not put it in an annuity and never work.
because young teens are going to understand what this "investment" stuff is.
but at that age, if it's any kind of decent loot, shit yeah it'd build for awhile. I bet it was the contents of a single drawer though, so probably nothing all that serious yet enough for the young girls to stare at the amount with a look of intense glee. Couple thousand maybe?
That is, if the teller at least wasn't brain dead. Who knows. If they walked away with tens of thousands or more, the teller should be locked up in a mental ward. "An undocumented sickness as of yet determined and to be the subject of much needed research."
... seriously though
Tellers should be told to sit there with a blank face, and simply say "no" if all a would be robber does is slide you a note.
I'd demand to see that piece of cold steel before even looking at where the money stash is. And in the mean time, contemplate pushing the silent alarm. Might push it, might not, depending on the way they were behaving (little ticks aren't that hard to detect if you pay attention to people) and depending on the likelihood of their ability to conceal a weapon somewhere.
They do have those silent alarm panic buttons under the teller spots like in the movies, yes?
But anyhow, I'd definitely take no action toward awarding them loot until I was given at least a glimpse of a weapon.
Yes, sometimes such actions like that might get one shot by someone who does have a weapon and panics, but I can act brazenly like that when it comes to threats.
this is how you do it
