Many years ago when i used to manage off-licenses I was held up by armed robbers it is a horrific experience having a gun held to your head and one that takes a lot of time to get over
Fortunately things like this are quite rare in my neck of the woods but there was an incident 15 years ago when a local driver picked up a fare from the Police station he dropped them across the road from Corby police station at which point they put a knife to his throat anfd robbed him
it turned out that the knife had been handed back to the passengers at the local police station because it was small enough to be legal and Corby police were unable to trace them even though they had been arrested and then released at our local police station
