Holdup at the Holdup

"Everybody hit the deck!" The armed robber shouted.
Everyone lay on the floor apart from one elderly man.
"Open the safe, old-timer, and fill this bag with cash," the robber said.
"We don't have any money, would you like me to put some sausage rolls in your bag?"
"Sausage rolls! Quit stalling and fill the bag or I'll blow your freakin' head off."
The robber approached the old man and pointed the gun at his head.
"I've told you already, we don't have any money."
"This is a bank, isn't it?"
"Yes, this is a bank - a food bank."
