If I'm driving, writing or in the middle of an interview, the phone can go fuck itself.
Ditto for restaurants or any other place where it's reasonable to expect some peace and quiet.
I cannot stand having to listen to one half of a conversation about absolutely nothing. :angry:
And don't get me started on cell-phones and driving. :rant:
If it's an absolute emergency or a call I have to take, I'll step outside to handle business.
No one else needs to hear it, IMO... and that rule should go both ways.
