If you have two dollars, you can buy two bottles of soda. You drink first, and then you take two bottles. At this time, you ask the boss to lend me a bottle of water first, and I will return it to you after three bottles. The boss said: fuck off! Therefore, subjects can only drink two bottles of water. So the landlord can only drink 100 yuan 149 bottles of water, and there are two bottles left.

Official positive solution:

Under the spring breeze of our socialism, how can our shopkeepers be so mercenary? They must serve the people wholeheartedly! Then, the boss agrees to lend you a bottle of water first. In this way, the subjects drank three bottles of soda for two yuan. So 100 yuan, there is no doubt that you will drink 150 bottles. By the way, there is not a bottle left.
