"Asking for Angela" is not a periods-related euphemism, but a code word to ask bar staff to assist in removing you from a dating situation that you feel is unsafe.
Pharmacia, on Sarsfield Street in Limerick, is encouraging men or women to use it in any sticky situation.
"If at anytime you are feeling unsafe in Pharmacia and need some help you can alert a member of staff here by asking 'Is Angela working tonight?'," Pharmacia staff wrote on Facebook. "The situation will be handled discretely and with no fuss... We have yet to deal with this issue but feel its important to have a procedure in place as a safety net.
