Can't people read?

I'm sure not all smokers are inconsiderate idiots, but it seems that many I encounter are. At the airport last Sunday, I couldn't help but to shake my head at the smoker in this picture sitting on the bench that says "Thank you For Not Smoking". It was kind of tricky to get the picture without looking too suspicious. Click on the left picture and then look closely at the bench; an enlargement of the sign is in the second picture.
