I feel for the guy when he said he would stay up at night trying to figure out how he would keep is bar open because his business was doing so bad. If it's now legal then he isn't doing anything wrong. The question at the bottom of the article asked -
Would you patronize a bar that allowed people to smoke pot? Yes or No
My answer would be yes. I have went into bar and grills where smoking cigarettes was allowed and I don't smoke. If I like the establishment then I will go in.
