The FBI says the modern bank robber walks in, gives the teller a note, takes the money and leaves within 90 seconds. He never carries a weapon and gets less than $2k, but if he's reasonably smart he can rob 30-40 banks before being caught.
That's terrible pay, when you think about it. You're always on the road, and you spend a couple days on each bank. You might as well sell insurance for a living.
I think robbers know that, too. Bank robbing is old school. Robbing Gas pumps also has gotten too risky to be worth the trouble; they keep way less money around than they used to and they have video recorders everywhere. So, nowadays, your best bet is mom and pop shops, at least that is what I read in the papers :-)
