"Being Too Nice..."

I'm at Borders sitting at a smallish table.  For some reason, people think I'm nice and always ask to sit with me.  Of course I smile and happily go out of my way to move my stuff, chairs or large furniture to make room for them.

Today a seemingly nice lady asked to sit at my table.  I said, "Oh, of course," making room for her.  Oddly, out of the three empty seats, she chooses to sit in the seat RIGHT next to me, puts on headphones and blasts her music so loud I can hear it word for word.  

I've got two columns due tomorrow and I'm listening to Borders music, her music and her breathing.  I kindly motioned for her to turn her music down a bit and she gave me a dirty look with some weird type of growl.

I again asked her to turn it down a bit more and she takes off her headset and says to me in some thick Argentine accent, "It's a FREE country!"

Wow.  Okay.  Am I too nice?  I refused to get up, so I began to make the 30 phone calls I was waiting to do till I got home.   Boy she was happy.  She ended up moving two tables over (I can still hear her music) on the way banging my table so many times it almost broke.

I'm done with sharing my table.  Next time I'll first screen them, make sure they aren't going to be listening to music or talking on the phone.  But I think it's better to go drastic, like start crazy coughing and barely be able to say "I have pneumonia  and still contagious."   Or I'll start picking my nose and without looking at them say "My imaginary friends are already sitting with me and they don't like company."
