It's rude to smoke around others.
James, a chain smoker, hasn't had a cigarette in over two hours while at his friend's house.
James wants a cigarette immediately.
James excuses himself and goes into the garden to smoke.
James pulls out his cigarettes and starts smoking inside the friend's house.
James' friends call him on his phone, so he can still hear their conversation.
The friend scowls and makes James go into the back garden.
