From Chapter 2:
It may be noted, by the way, that the gallant had no hesitation about smoking in the presence of ladies. Gostanzo, in Chapman's "All Fools," 1605, says:

And for discourse in my fair mistress's presence
I did not, as you barren gallants do,
Fill my discourses up drinking tobacco.

And in Ben Jonson's "Every Man out of his Humour," 1600, Fastidious Brisk, "a neat, spruce, affecting courtier," smokes while he talks to his mistress. A feather-headed gallant, when in the presence of ladies, often found himself, like others of his tribe of later date, gravelled for lack of matter for conversation, and the puffing of tobacco-smoke helped to occupy the pauses.

When our gallant went to the theatre he loved to occupy one of the stools at the side of the stage. There he could sit and smoke and embarrass the actors with his audible criticisms of play and players.

From Chapter 5:
The French traveller, Sorbière, who visited London in 1663, declared that the English were naturally lazy and spent half their time in taking tobacco. They smoked after meals, he observed, and conversed for a long time. "There is scarce a day passes," he wrote, "but a Tradesman goes to the Ale-house or Tavern to smoke with some of his Friends, and therefore Public Houses are numerous here, and Business goes on but slowly in the Shops"; but, curiously enough, he makes no mention of coffee-houses. A little later they were too common and too much frequented to be overlooked. An English writer on thrift in 1676 said that it was customary for a "mechanic tradesman" to go to the coffee-house or ale-house in the morning to drink his morning's draught, and there he would spend twopence and consume an hour in smoking and talking, spending several hours of the evening in similar fashion.
