If you need help in a bar, a discreet phrase like "Can I ask for Angela?" will let staff know you are in an uncomfortable situation, as seen on the Metropolitan Police website and other sources. You can also use the term "angel shot," and staff will help discreetly by getting you a taxi, contacting friends, or ensuring your safety without drawing attention to you. If you don't know if the venue participates in these initiatives, it is still best to approach the staff and tell them you need help directly.
