– It’s obviously cigarette ash. If you look at it slowly, you can be certain.
– Only embers fall. The cigarette remains in his hand.
– Is there a problem with ashing in the smoking area? Ask smokers around you.
– Can’t you see the cigarette flying? If you can’t see it, go to the hospital. Either cataract or schizophrenia.
– I see now that the manager was in front of him. The manager should’ve covered him.
