I was at a cafe enjoying breakfast. The cafe is big, got around 25 tables in. I was the only one in the cafe. A couple, came in, placed their order at the till and came and sat at the table right beside me! They had 20-odd other tables to choose from. My table wasn't in an enviable position in the cafe, no views out of the window, nothing special about this area in the cafe, yet they chose to do this. Why?
