Two armed robbers made off with hundreds of pounds after threatening managers and staff at a roadside cafe.
The men walked into the Little Chef on the A35 in Corfe Mullen, Dorset, and demanded the keys to the safe, which a member of staff handed over.
They escaped with about £500, according to Dorset police.
Detectives urgently want to hear from anyone who may have seen the robbery or witnessed the men escaping from the scene on Saturday evening.
