Flower Bandit

We checked the video twice.
A man walks into the bank, gives the teller a rose, and she hands him all the cash in the drawer.
He kisses her hand and then walks out to the street, vanishing in the crowd.
No alarm at all.
Nobody knows who he is. His face is all over the news, but he’s not armed or dangerous.
The tellers refuse to say anything about him, but they insist on keeping the flowers.
We’ve checked for fingerprints and DNA… nothing comes up.
What’s curious is that since he started, sales of flowers have gone up.
