Knife-wielding robbers got away with £20 cash and about £300 worth of cheques during a raid at a Boston shop on Friday morning.
The robbery occurred at Ali’s Food Store, on Freiston Road, shortly after 7am.
Two men entered the shop and threatened the owner Ali Nassertayabali with what he described as ‘kitchen knives’.
Mr Nassertayabali,49, said: “I was just opening the shop, putting signs out, and they must have followed me inside. As I turned around there were two blokes with knives.”
He said the men stood silently and pointed to the till with the weapons.
He handed them a wallet containing about £20 cash and two cheques for £150 which he had planned to use to pay the milkman and they left the store.
“If someone points a knife at you, you just do what they tell you,” he added.
Mr Nassertayabali, who was on his own at the time, said he thought he had been calm while the incident was ongoing.
“I was surprised but I pressed the panic button,” he explained.
“After, when the police came, that’s when the adrenaline came in. I was shaking.”
He said the police were ‘really good’.
A force spokesman issued an appeal for witnesses to the robbery.
The men are described as tall and white and were wearing long coats, caps and sunglasses.
The spokesman said the men left in the direction of Burgess Pit.
Witnesses should contact Lincolnshire Police on non-emergency number 101 quoting incident number 54 of June 14.
