Smokers say that they are more sociable creatures. Offering someone a tab is a friendly and increasingly generous gesture. Non-smokers could try offering their limp sandwiches around and see how many takers they get. It's an argument that will never be settled, like whether or not Geoff Hurst's second goal crossed the line or not. If somebody wants to spend their money on cigarettes, let them.
Some people devote their hard-earned wages to other equally bizarre hobbies.
Like ballroom dancing. It's all part of life's rich tapestry. Non-smokers shouldn't bitch about secondary smoke and smelly clothes. Stuff like that. With increasing demands on our time, the concept of simple pleasures could be set to go the way of the Sega MegaDrive.
