Personal space...what's that?

As you may have read earlier, I have 'issues' with being touched or hugged. The other night I stopped by the library to pick up some movies I had requested. I was standing at the counter, waiting patiently to check my movies out when this old man approached on my left. Instead of waiting in line behind me like a civilized human being everyone else, he came up right next to me, WAY too close, and just stood there with books in his hands, ready to check out. He reeked of smoke and bad breath, and he obviously had no concept of personal space! And he just stood there, creeping me out waiting. He was quite literally RIGHT. BESIDE. ME. As if this wasn't bad enough, a small child approached on my right and also stood there next to me. If I had tried to move in any direction, I would have brushed up against one or both of them. Do these people not know what a line is? As if this wasn't bad enough, ANOTHER old man approached and stood just behind me to my right. Again...not in a line. I've never seen such a chaotic, messy line. Not even among the preschoolers in Olivia's class!
