the bank robber

I, like many others, are short of cash
the idea of robbing a bank at gunpoint is repellent
and I hate guns.
I have a better idea, in the evening when I go for a walk
leaning against a bank-door in the hope they have
forgotten to lock the door.
There are many banks in the street where I live.
To avoid attracting attention, I lean only at a door
of a bank once.
There must be one sloppy enough to forget to close the door, and if the safe is open, I´m home.
I have two plastic bags for this purpose.
Should I be lucky I will not be greedy fill the bags
and go to Spain, no, only enough to pay the electricity bill
gas and rent; and enough for a bottle of posh wine
and change the tires of my car.
