In the words of Stephanie Tanner - How Rude!
This morning I got on the El. In the seat in front of me there was a woman, about my age putting on her makeup. Not a big deal, but she did have her makeup case and purse and bag sprawled across the seat next to her. Train etiquette says not to take up an empty seat with your purse so that there's room for others to sit there.
Another older woman gets on the train and clearly wanted to sit in the seat next to the makeup lady. Now granted, there were other seats around, but maybe she wanted this specific seat because it was a window seat, or facing forward (some people get sick riding backwards). Either way, she asked the young lady if she could sit there. Train etiquette also says you should give up your seat for the elderly. Though it doesn't specifically address this rule to purses, it's safe to assume an older lady has more right to the seat than a bag does.
The girl actually told her no. "I'm getting up in a couple of stops." Then she just continued to put on her war paint for the day. The woman was sort of just dumbstruck. She stood around waiting for the girl to move.
Then I remembered that I too had been denied a seat by this jerkpod in the past. Just remembering it, I think I verbally uttered, "Well that's rude." I hope she heard me. Finally when her stop came, in a huff she gathered her stuff together, gave the old woman a dirty, "thanks for inconveniencing me" look and brushed by her, smacking her shoulder against the old woman's shoulder as she stormed off.
Myself and the other passengers just shook our heads at each other. Seriously, how hard is it to have a little consideration?
