I had a job and noticed that this one employee would often step outside for a smoking break, I then noticed it was longer than your typical break and more often. So the next time he stepped out I joined him, no smoke just talk. When we came back in the boss asked where I was, I said on a smoking break, she said you don't smoke, I shrugged and went back to work. From then on the other guy kept his smoking to his regular breaks, he later told me he wasn't mad, he'd been trying to cut back.
