Smoking/No Smoking?

Went to the golf clubhouse's restaurant this afternoon. I was waiting for my kids to finish their golf. Settling comfortably in a plush couch sipping my avocado juice, when 3 korean guys came over to a table next to mine. All of a sudden, I could smell cigarette smoke! I was sitting in a non smoking part. The resto is pretty big, and it has a smoking section. It was ridiculous! They can even sit outside for goodness sake! So selfish.
