Hmm i activated the two bonus pop up so i got profit 2/beer+11/wine+15/whisky (full upgrade building + SP1-2). Max earning = beer(120/1)*2*3+wine(120/6)*11*3+whisky(120/10)*15*3 = 720+660+540 = 1900-120 = 1780/2 = 890/hour
This is max earning from selling drink only, and my average is 700/hour, i play around 15 hour so its 10500 + ref + bonus = 20k per day maybe
