Irritating airport experience

So while waiting for my westbound flight, I purchased a NY Post as I usually like to read a tabloid when traveling. I put the newspaper on the empty seat next to me. There is a woman sitting on the other side of the empty seat. She is eating a salad. I go to get some water, leaving my traveling companion sitting next to my bags, one seat over from my paper.

I get back with my water and the woman had slid one seat over and was reading my newspaper, pulling apart one section and leaving on the chair where I had been sitting. I picked that section up so I could sit down. I told the woman "can you give my paper back when you're done?" She murmurs something about it being there. I say "oh well, I don't mind sharing."

Not two minutes later, the woman folds my paper into quarters, takes out a pen and starts on the crossword. she works on it for two minutes. Then she stands up, walks over to the trash with my paper and throws it out.

Some people I don't understand.
