Masked armed robbers tried to stab a cashier after he refused to turn on the fuel pump during a raid at a Heckmondwike petrol station.
Two men threatened 28-year-old Aamir Adam with a knife at the kiosk of the Texaco services in Walkley Lane before stealing cash from the till last Thursday.
The robbers entered the services on a motorcycle wearing helmets with balaclavas underneath.
When Mr Adam, who lives in Dewsbury, refused to turn the petrol pump on, one of the men jumped off the motorbike and tried to stab him.
He said: “One of the men tried to grab me and swung a knife at me.
“He held me with one hand and tried to stab me with the other.
“I was scared but I dodged the knife when he swung it and ran away. I was lucky to get away.”
While the robber attacked him, the other held the kiosk door open so it couldn’t be electronically locked.
Mr Adam said: “The other guy was holding the door open and controlling it.
“I think he was watching what happened incase he had to jump in.”
Mr Adam then fled to ElectroPhix phone shop next door and the robber stole cash from the till.
He said: “I’ve never had anything like this happen before, I was totally shocked.
“I didn’t see where the knife came from but it was quite long, like a kitchen knife.”
A red motorcycle was later recovered by police.
The services are owned by Mr Adam’s dad, Younus Adam.
Mr Adam said they were improving security at the services and considering putting a cover over the counter to deter thieves.
Police are appealing for witnesses to the robbery that happened at 3.12pm.
PC Nicole Senior, of Kirklees district robbery team, said: “This incident took place at a busy time of day and I am sure that someone will have witnessed some or all of what happened.
“I would urge them to get in touch so we can bring the offenders to justice.”
Police said one of the men is white, in his 20s and was wearing an orange coloured helmet.
The other man is in his mid 20s, of slim build and around 5ft 8ins tall.
Anyone with information should contact PC Nicole Senior by calling 101 and quoting crime reference 13150121354.
