A distressed woman needing help to escape a potentially violent date used a private signal to the DJ at a Liverpool pub to get away.
She was saved by asking the DJ if Angela was working and, knowing immediately what she meant, he helped her out of the difficult situation.
At the city centre pub, the DJ responded by saying yes, Angela was working and told the nervous woman to get inside the booth with him.
He then called for help from security, and asked a guard the same question, which led to the woman being helped out of the back of the venue and into a taxi.
The man, who shared the episode on a Liverpool hospitality industry Facebook page, is now calling on other venues to train its staff to know what to do in these types of situations.
According to him, when the woman's date returned from the bathroom he was told to leave by management and then turned "violent" when security stepped in.
The Ask for Angela initiative was first set up by Lincolnshire County Council and in December 2016 it went nationwide.
It calls for people to ask for help by going to the bar and "Asking for Angela" - a phrase aimed at alerting bar staff to a problem so they can try and help out.
The idea is that trained staff will then take them to a safe space where they can explain what has happened and get a taxi, friend or family member to pick them up.
The worker can then tell the other person involved to leave or phone the police if they believe there has been a criminal offence.
In Liverpool, multiple bars including MOJO, on Back Berry Street, have shown their support for the campaign and trained their staff.
