He's a nice guy, just ask these people, whom he ran back to meet.

The actor was in Chicago to promote his new mezcal line, Dos Hombres, along with his costar, Bryan Cranston, who was at the same event.

The video shows AP jogging back to say hello to people who missed the window, not being able to see Bryan andAaron in the flesh.

You can tell the people appreciated it.
