Give me an excuse to leave!
for those situations when you really wish your phone would ring and give you an excuse to leave,. ie. generate a "get out of this conversation/date" call or message...
This excuse to leave is depicted well in the Flic promo video where we see the ego-centric blind date yapping all about herself. He hits his Flic on his belt, suddenly his phone rings, he apologizes, he walks away, phone to ear.
