(My first aibu - am bracing myself) 
Today, I was parked outside a hospital waiting for my parents to come out. Right outside the entrance of the hospital and for about 50 metres, there are numerous signs (I counted eight from where I could see) signs saying "please do not smoke here" and "no smoking". I was waiting for about ten minutes, and I saw lots of people (15) smoking around the whole no smoking zone inc. several people (6) actually smoking next to a no smoking sign. I was partly amused by the irony of it but I also thought there must be a reason why it's a no smoking area, so why are they smoking there? Why could they not walk a little way and smoke where there were no signs? Just to let you know, the whole entrance area inc. way beyond the signs is sheltered and it was not even snowing nor raining.
