Ask for Angela

The UK launched an initiative in 2016 to prevent sexual assault. The initiative involved placing posters in strategic locations like restrooms notifying patrons that they can ask a staff member for “Angela.” The name functions as a code word indicating to staff that the person feels unsafe and at risk for sexual violence. Employees can then help the customer escape the unsafe situation. Have you heard of anything similar in the United States? If not, do you have any ideas or suggestions for similar initiatives in America?
