"He does it all the time, he's out there constantly, multiple times a day," said Caroline, who didn't want her last name used.

"We've seen him having two in a row. He'll have a couple of cigs as he sits there. Or he'll go away and then come back again.
"To his credit he does puff it out the window," Caroline said.
"He looks pensive. He's not relaxed, no. Sometimes you can see him looking back to the door a bit, like he's going to be busted.
"We thought considering everything he's probably a little stressed."
