Go outside, if weather and inclination permit. Go into a separate room if going outside is not convenient. Keep track of your smoke if you light up inside. Take note of your neighbors. Smoking and eating do not go together, ever.
Smoke kills the sense of smell and therefore taste.
Be aware that cigar smoke is denser and heavier than even cigarettes, and can be more annoying to smoke haters. Remember the golden rule whenever it comes to personal habits in public. These days, fewer and fewer people smoke, and the places where they can smoke are becoming limited. As a smoker, especially of cigars, not disturbing others has become a matter of being extra polite and considerate. Smoking on airplanes has been all but outlawed.
