Since you don't use yours in stores, can I take it your don't talk at all in stores either? Because really, what does it matter if someone is talking to an electronic device or another person? It's really not your business...seriously, it's not. The point is, you are not the national arbiter of cell phone courtesy.
As for the rant, it cuts both ways. You rant...I rant...we rant. It's all part of the debate. I'm not saying your are a bad person, maybe just a tad too concerned about how someone else is exercising their personal freedom.
It's nothing personal. We can still have a beer together...if we can find a bar quiet enough for you. :)
ROTFLMAO. That was an awesome last line. I loved it.
