@@$%$#$%$period&*^&(*(*&

I despise using periods in phone numbers. It makes them useless and makes me think people who do it are lazy jerks. I just got a list of contacts to work on and all the phone and fax numbers were period separated like 123.456.7890.
I spent half an hour trying to salvage the mess before I sent it back and told the guy to fix it if he wanted me to work on it.
