I hate cell phone people. Not all people with cell phones, but the people who think nothing of taking a call in the middle of a conversation with the librarian that's trying to help them find books. She didn't even apologize (which is crap anyway--if you KNOW something is rude, you shouldn't do it. DUH).
I fixed her, though. She tried in vain for fifteen minutes to make eye contact with me so that she could jerk her head at the computer--to politely let me know that she wanted to check her stupid books out, but I wouldn't look at her. So she had to disconnect her oh-so-important phone call to check out.
HA! I win.
Even with the passive/aggressive winning, I think it's going to be a bad day.
