I grew up in Europe, where the concept of sharing a table at a bistro or what not is, or at least when I lived there, the norm. I have no problem sharing a table, and no problem chatting or not chatting depending on the other person's mood. But heck, it can be a great way to meet new people, even if just for a short time.
