Strange Man at Starbucks

This is the forth time I have seen the white man in his 60s sitting in Starbucks pretending to talk on the phone. The first time I thought he did until he took his hand away from his ear without a phone in his hand. He was just rambling about the government, economy and some sort of CIA. I didn’t quite understand what he was talking about, but I hope that he doesn’t do anything crazy at Starbucks.
