The foreman was very angry when he found out that the homeowner bought water for the workers and master craftsmen. He went to the lady of the house and asked, "Did you buy water for them?" The lady said, "Yes." The foreman said, "We prohibit homeowners from buying cigarettes, water, or food for the workers and master craftsmen. Why are you breaking the rules?" The lady said, "I think they work quite hard." The foreman said, "Rules are rules, and they can't be broken." "If they dare to drink a sip of your water, I won't pay them a single penny after the job is done." The lady said, "Alright, then I won't pay you a single penny for this job." Why didn't the foreman allow the lady to buy water for the workers to drink? $ETH
