Oh my goodness. I just checked my smart phone -- how did that information get there? Thank goodness you pointed that out.
Reasonable discussion doesn't have to portray the other discussant as a doofus, ya know!
But this was about answering the phone. Not looking up sensitive information, scrolling through emails, and sending texts. The CM was apparently allowed to hold the phone and give it to the owner, so this isn't a "no touching at all" policy, and I don't think the OP was insinuating that the CM should've looked through the contacts and other information to figure out the owner's identity. .
