I'm not sure that does sound patronising to be honest?
I'm an ex smoker. I smoked for over 20 years.
When I first started, smoking was totally acceptable everywhere. There were ads on TV, everyone who smoked did so indoors, in restaurants, on buses and trains, in council buildings...even in shops.
One of my earliest memories of Infant and Junior school was taking messages to the staff room for the teacher, and the wall of smoke that hit me as the staff room door opened. You always knew when the Head Master had been in the coridoor before you because of the smell of his pipe smoke.
But towards the end of my smoking years, I actually did feel embarrassed at times...standing outside a pub, restaurant, someone's house, hospital, wherever really...puffing in all weathers.
It really actually made me feel as though I was a 'proper' addict for the first time ever.
And yes, I personally found that embarrassing at times.
