(From Google AI--- no apologies for using it here,
I had heard about this before but couldn't recall the details):
The most common keyword phrase is "angel shot". Ordering an "angel shot" is a discreet code used to signal to bar staff that a patron feels unsafe and requires assistance without alerting the person causing the distress.
The type of assistance requested is often specified by how the "angel shot" is ordered:
"Angel shot neat" or "straight up" means the customer needs a staff member to escort them safely to their vehicle.
"Angel shot on the rocks" or "with ice" indicates that the patron needs staff to call a taxi or rideshare service for them.
"Angel shot with lime" or "with a twist" is a signal that the patron is in immediate danger and requires the police to be called.
Important Considerations
Check for signs: Bars participating in this initiative often place discreet signs in the women's (and sometimes men's or all-gender) restrooms, explaining the code word and the types of help available.
Staff training: The effectiveness of this code depends on the bar staff being trained to recognize and respond to the phrase appropriately. While the "angel shot" has gained popularity, not all bars may have a formal protocol in place.
Direct communication: If a bartender does not recognize the code, or if you are in immediate danger, it is best to directly tell a staff member or security person that you feel unsafe and need help, or call the police directly.
