How often do you keep casino tab open just because there might be a rain coming soon?

Its usually a few cents or maybe dollar in some lucky cases but somehow you end up checking chat every 10 mins... that's it, you are on the hook. are these actually 'generous' rewards for community or just another clever way to keep people on the site longer?
cause lets be honest, the longer you sit there watching other people play the more tempting it gets to place another bet yourself...
And another layer question - do you actually enjoy hanging out in chats with others or are you just waiting for the next free drop?
