It's terrible that people feel the need to take such measures to feel/stay safe but I understand why they do so I never begrudge them for it. I just go into a date expecting her best friend to know my name, face, and address; or wherever it is that we happen to be meeting. And while I find people spending time on their phone during a date to be annoying, for all I know she's updating her friend on her continued safety so I don't make a deal of it.
